Thought I had better get on and start a resto thread, because some have been asking and also it is a good recall for the years of pain and anguish to follow.
I was on here as DavidGT73 but changed to to correspond with the correct year, 71, dad got confused and thought it was a 73.
The car was a resto my day started almost 10 years ago but old age and his increasing at the time motorbike and moped collection stalled it.
He now felt too old and lost the enthusiasm to go into the cold garage and finish it so I have inherited it, to speak.
Not many before phots as dad didn't take that many but a brief resume is:-
1971, non OD, Brown rusty GT6.
Dad stripped it and has replaced floors, rear wings, patched the roof section, part replaced the lower section of rear valance, inner where arches new, new bonnet and quarter valances.





He got some years ago a s/h chassis converted to take his or the new suspension, however when I started to mock up the bonnet with the body and doors nothing seemed to fit. It transpires that he had fitted the new rear wing skins slightly too far into the door aperture, I now have found after reading various bits on here that the skins can be the wrong size and not fit well, and I thought it was just the American Mustang panels that were a poor fit. So with the bonnet and tub bolted into the best position possible the rear wing was cut, bits removed, new bits let in and then leaded to make good.



No going back now



And a bit of lead work to make good

The other side wasn't that bad but the welding needed a bit of making good and then to finish a skim of lead.
I think they were originally lead loaded here as I found old traces on the top of the B post, so I followed suit.





And making good, The top of the door trailing edge here I had to let a piece in as it was starting to get thin.

As a foot note I'm not sure how much you lot like photos or long winded or short write ups etc. Let me know so this doesn't make good nodding off material.

Cheers

David

The doors were OE and in good nick and I didn't want to replace a skin just for the sake of it.
The O/S door wanted a repair on the lower section and that was it really.





Cocked up on the radius and had to use the shrinking blade to pull it in a bit.



And fitted ready to be fettled. Also the gaps were terrible all around, having read on here that this was the norm apparently I have tried to set about correcting this, this door has had the old welding wire trick to close up gaps and get them parallel without the use of filler etc.

Just make sure you wash off all the flux before you apply lead, a soda mix is good to neutralise it.

That's right, any good alkaline base mix will do, an old boy who taught me how to do lead work about 35 years ago said that good old fashioned washing powder mix was one of the best things, and cleaned his hands in the process before he went home, Or vegetarians pee, this is alkaline , the washing powder is great, never had the nerve to try veggie pee.

The alignment of the door to sill to bonnet was a real issue, I'm not sure if the sills were slightly out or dimensions wrong or perhaps just fitted a bit out, or they just don't give the satisfactory gap wanted, however as they were well and truly on the only option was to correct some of the angle gaps with a welding weld trick.



The curve runs neatly with the door bottom and now runs up and aligns with the new bonnet edge.

The sill wasn't quite high enough to the door bottom, so this was raised the thickness of a welding wire and then sanded down to give a parallel gap.

.

Once ready I will lead most of these gaps and making good.

The O/S already done to meet the curvature of the door bottom and to get the lines running up into the new bonnet trailing edge somewhere reasonable

The bonnet was proving to be a real issue and no matter how I tried to adjust this I could not get the bonnet edge close to the scuttle or door.
Any attempt to move it cause real issues with the alignment of the sill into bonnet wheel arch alignment, into the bonnet wheel arch alignment into front quarter panel, or to make matters worse really cocked up the alignment and view of the bonnet with bumper etc.
Its a job to explain but any of you who must have done this will know what I am talking about.

After a week of evenings bu&&erring with this it transpired that the edge of the new bonnet was 1/8th inch shorter on the O/S and the top of it where it meets the scuttle/door top edge was a different shape, Woooooooonderful.
As dad bought the bonnet over 8 years ago sending it back wasn't an option so I had to remove the top small bit of return edge of the bonnet on the o/s trailing edge, welding wire to the rescue, welded to extend the trailing edge and then weld back on the return to finish the bonnet. Fits like a glove, not sure if this shows it or not.

No door but you get the idea



And now with a quick fiddle we get a fairly decent bonnet to bumper and to quarter valance gaps.

What an absolute nightmare David,i'm surprised the Heritage bonnet was out that much! I've done a few jobs on a couple of these over 25 years ago now and always found using the Original panels an excellent fit mostly. Don't forget to Galvanise it when your finished to add a bit of Vorsprung durch Technik. Lol .  Even though we love an Audi or 2   (no more rust and welding when i switched over) you've got to agree a GT6 Mk3 is a stunning looking car when done right,i've always loved them.Keep up the good work mate! 👍

I wont be galvoing it, as any paints like this can lead to adhesion problems of other products, although believe it or not good old screwfix do a really good zinc rich spray. I tried one as a short cut measure years ago as I was out of weld thru primer, crikey it really is zinc rich, so all of the bare metal on patches and prior to welding get a good old coat. Any welding will burn off on the welds but this is good gear.

I use epoxy primers now and have done so for years, the old acid etch stuff was superseded by this years ago, the Lechler and Mipa epoxy sealer/primers are great products, and fantastic for bare metals and a good base prior to any filling and paint process. Yep the Audi is holding up fantastic at the moment, and its on the list after the GT6, and the wife has chosen the colour as the GT6 will be her car.

I have no idea, my dad purchased this lot I think over 10 years ago, I think he got the lot from Rimmers, or it could have been he used Moss, like I said I cant remember, and I think he has forgot, we keep finding boxes of bits though.

Not OE but the Memsaab has chosen Midnight Blue, BL/Triumph blue, very dark, She wanted it black but 1 black car in the family is enough.

So not much to show for the last few days apart from prep work, sanding and grinding, and more sanding, you get the picture.

Managed to get the tub on the rotisserie though, adapted the Mustang brackets without too much work, and make the job a lot easier.

The inside was more of a pig due to all of the sharp edges and bits designed to cut and stab you on purpose.

However it does mean I was able to get a good coat of epoxy sealer/primer everywhere, a great base ready for filling and shaping.
This was the Mipa product, I usually use the Lechler epoxy LS107, however a mate recommended the Mipa,. Goes on well but dries flat, even though is still soft to touch till dry. The Lechler has a sheen finish, clear and tintable which I think I prefer. The Mipa comes black, and by f does it stain the skin, the glove had a small split and nothing is shifting this paint, I suppose its a good recommendation that it will be good on the car.

Very nice work, I'm a couple of steps (years) behind and just designing the rotisserie. How high up is your CG from the bulkhead mounting brackets?

I will have a measure tonight.
It is pretty close, I can swing the body with one hand.

Its a very heavy duty rotisserie, I built it to cope with a 66 Mustang, so if there are any slight misalignments the structure doesn't move.
I should imaging if you build a lighter weight one then the C of G would need to be perfect to avoid any movement or twisting I would have thought.

That will be great!

Since my chassis is twisted, I plan to make a sub-chassis to mount the tub on to repair. This will sit below the floorplans and therefore lower the CG but your dimension will give me a maximum height.

What steel dins did you make yours from? I'm planning 70mm x 70mm x 3mm

Hi
The front measurement from the CL of the pivot to the bottom of the front mountings ( if that makes sense) is 14"
From the CL of the rear pivot to the centre of the rear bumper mounts is 4"
This brings both rotisserie pivots CL in line.
I think it is slightly bottom heavy, but only slightly so you could reduce these measurements by 1/2 to 1" but is would be trial and error.

Not sure if you have done many of these before but even with a roof I wouldn't rebuild on a rotisserie. Always rebuild it from a level you know is correct. I have a square adjustable frame made from 9x6 steel I section, I can pull the side in and move the ends about to accommodate most vehicles, this way all measurements are taken from this so you know they will be the same o/s and n/s and front to back.
If you cant do this then I would suggest getting the chassis you are going to use, check it for level and square and build from this but use steel or solid packers, not rubber etc.
The last thing you want is to weld it on a rotisserie and find it pulls out of shape when bolting back onto the chassis.

I can get some more dims tomorrow on the box section.

Cheers

David

Excellent, thanks for that, it'll give me a starting dimension for the CG.

I'll be heavily cross bracing the shell on the flat so hopefully repair on sub-chassis should be OK......fingers crossed

Slow progress, only managed to get the seam sealing done inside and out, but made sure I got the most important seams and joints covered with my fav sealer, 3M 2k, fantastic sealer, modern OE finish I know but the best on the market.

Once ready the floor will get a coat of grey Raptor stone chip / bed liner then we are going to finish it body colour.

Here you go



Left the bit of paper at home with the dims on, but I seem to remember these were 80mm and 70mm, I think the 80mm was approx. 2.5 or 3mm, leaving a nice gap to allow the inner box to slide in.
I think I went to 3-4mm for the 70 mm as these would be taking most of the bending force. Anyway its kin heavy but extremely safe and solid. The triangulated box supports are 50mm x 2.5mm

The pivot tubes I have a ptfe strip bearing each end of the pivot tube, most home jobbies I see are just greased metal to metal, with the 3-4mm ptfe strip bearing I can replace this at any time if it wears and it also means I don't have cacking grease around the car while doing the body work and it rotates nice and smooth.

Thanks

Off on hols tomorrow so will do a bit more on the photos front when I get home.

At the moment the body is back on and I have fabricated new seat belt mounts sop the wife can use inertia belts without the need to reach over her shoulder to grab the clasp/pin whatever.
Did a mod to mount the top fixing up high almost like a production car and reinforced that area of roof member. Given the top mounting bolt is under a shearing load rather than tension ( pulling ) the frame is super strong. Tried to take a couple of pics but the shots just come out dark, even with a flash. The area where the bolt comes thru the headlining we have fabbed the seat belt bolt mounting so it is just below the headlining so the headlining doesn't get pulled out of shape. Good old dad is turning up a decorative white PTFE washer to finish the headlining where the bolt passes thru to neaten it up.

Also found a sill seam/flange finisher which will work nicely. From what I can see the sill to floor seam was covered with a S/S finisher which is hard to get hold of now, so we have been looking for an alternative, our local metal fabricator man supplied a real nice length of U channel steel which fits perfectly over the seam. I know it should be S/S or that finish but we don't want the expense of chrome and zinc isn't man enough for that area so we have bu&&ered about and tried different things and its going to be painted body colour. Not OE but for the mock up it really neatens this up and looks nice to suit. Again, I will try some more photos when I get home from hols.
Cheers

I'm not sure I'm sold on the looks of the sill seam finisher, but then again my car has never had them.
That said, that seam is rather ugly.
The problem with the finisher is it is a nice moisture/dirt trap, perfect breeding ground for Rust.
I'm actually contemplating just getting some stick on plastic chrome door edging and just sticking it to the outside of the seam.

Was debating that for some time but its really easy.
When the car is fully primed its stuck on the rotisserie, flipped and the underside of the floor Raptor finish then top coat same as body, all 2k.
No hard edge mask on the body, just careful application underneath and allow feather out onto underside of sills etc but make sure inner and outer edges of sill seam/flange has good coat.
Prep and paint trimmed ready to go sill finishers, now the choice.
Either small drill holes in bottom edge of sill finisher, ( done before paint ) either spot fix with PU adhesive or use trim clips, same style as top wing finishers to attach trim finisher.
or my choice
Mock up and fit finisher, prep and paint, then fit finisher with  upper moulding trip clips, then using a grey PU adhesive carefully seal the edge of the trim to the flanges, pointy finger is best, push it in then wipe off excess so it cant be seen. Because you have painted the trim finisher first you can wipe the PU adhesive off easy with a good de-greaser.
Then when the body gets flipped over for top coat return mask off the rear of the already painted sill flange finisher, prep the paint on this front side,  the body can now be now prepped ready for paint and when you refinish no one will be able to notice the return mask on the bottom edge of the sill finisher. If it is a little bit harsh because you were heavy with the gun or forgot to remove the return mask and feather with some blend out thinner or slow thinner then hand off with G3 on this edge.

When I get to this stage I will put up some pics.
There are many ways for everything but this is prob the method I am using.

Ciao

The following might prove a suitable stainless sill finisher:

http://www.fhbrundle.co.uk/products/1504UFS6__Stainless_Edging_UFS6_12_70x3_30mm_Gap_Length_2540mm

At 3.30mm gap it's probably going to be a tight fit on the flange

That's a good find, thanks for the heads up.

£10 p&p and the chance of getting bent, Southampton isn't far and I'm always down that way, would be worth the money just to have a try,

Haven't done much or a write up as pics of rubbing filler and bodywork is as boring as doing it.

So the body is ready for some polyester spray filler and more blocking, but the hard work now means the poly will only hopefully need a 120 cut and finish.
Just have to finish the n\s head lamp finisher to the body as it doesn't fit as nice as I would like, will get a few pics of this area up later on.

One thing the wife wanted was a seat belt that she didn't have to reach behind for, bad back and all that. She used to have an MGB and this had the issue and became a problem and the belt always used to get dropped on the sill, shut in the door etc. So this time I have tried to set the seat belt fixings up much like an every day driver. The roof fixing was reinforced with 1/2" box along the inner structure top and bottom of the fixing plate, which in turn has the securing nut welded on the internal side, so it cant pull thru the plate. Also the majority of the load on any fixing up there will be a shear load on the seat belt bolt its self, so this isn't going any where. I also made up a locating bracket on the rear arch with 2 lug to locate the reel part of the seat belt, nut and bracing plate for this welded on the reverse of the arch.

Sorry the pics of this are not very good but couldn't get any light in to show the install.





This does mean we have to penetrate the head lining for the top bolt fixing but we have welded the support just so it is under the headlining and doesn't put the headlining under any tension or cause any of it to show thru. Dad is in the process of making up a nice white and black ptfe decorative washer ( choice which looks best ) that will fit just around the top fixing to make a neat edge, this will be bonded in place with a vinyl weld

Now finally managed to get some time to get the body and bonnet in polyester spray filler.

Put down a good coat of epoxy primer first over the bare metal and filled areas.







Re applied to the internal areas again over the bare metal and new 3M sprayable seam sealer and seam sealer

Then a late night but managed to get several good thick coats of polyester spray filler on. Such a slow process as the stuff is thick, even using a 2.0 tip and needle in the gun.
But 4 ltrs later it was done. Saturday will be another mammoth blocking session, rubbing most of the stuff onto the floor, dust up your nose and in every orifice.

Some excellent work going on there.  You obviously have plenty of bodywork experience, especially with paint.

I'm envying the smooth lines of the bonnet bulge and the crisp crease below the tailgate where roofline meets the deck.  I'm going to have trouble with those due to previous damage......

Looking forward to seeing it in colour.  What paint system are you using for that?

Thanks, I'm sure yours is just as good. I'm afraid skills come with old age, its a cruel toss up, at the moment I would love to take a few years off, but you can never have time back, bugger.

Thanks for the kind comments, I have been doing this sort of thing for as long as I can remember, I also turned a hobby into a business where I had a Classic Car and Sports Car restoration business.
I had the business for many many years but a combination of greedy landlord ( thought being busy meant £££££ ) too much work and a very young family meant one morning it came to a head, wasn't the money or the 12 / 14 hour days it was the getting cross with my little ones because I had quotes to do at home, VAT etc, went in the next morning and packed it all in.

If you can get most of the metal damage out of the rear you should be able to mask line the swage and block it back in, its amazing if you spend a bit of time with a long blade there on the polyester how much you should be able to pull it back.

I have never had a specific system as I use materials that I find the best, Polyester spray filler is Reface, really nice to work with, HB undercoat is either uPol or at the moment I have an old paint supplier that can still get DuPont HB medium to high VOC, old school 2K high build undercoats, its great stuff, so much better than the newer compliant low VOC stuff.
The epoxy sealer primer is Lecher 29107, blindingly good  product, use the clear and tint it to suit.
UPol hardeners, fast and med, I don't use Very fast hardeners as they can skin over too quick in warm weather causing solvent pop in some cases, the fast is quick enough to allow for solvent evaporation and a decent flowout. Top coat is either Standox or Sikkens, in some cases I will use ICI for satin black but I just don't like their material for some reason. If I'm doing a very special job then I will treat myself to Glasurit, my word this stuff is nice but it is horrendously expensive. The 66 Fastback Mustang I have just restored from the ground up I priced up the base coat in Glasurit and Standox, the Glasurit was over 3 times as expensive, Standox it was. All dry rubbing papers are Bullldog or 3M and all W&D ( I'm still old school wet finishing ) are 3M only.

I use the DeVilbiss Gti Pro guns with a T110 air cap at the moment, the air cap gives a great finish from the gun, in fact the finish from the air cap now has less peel than factory finishes.

Hope not too much info, but if it helps anyone.

Cheers
David

So not a lot of progress as other things have kept me busy for the moment.
Rubbing the polyester, wonderful job no one ever said, still you might think the fit and finish is good, but being the car is going to be Midnight Blue ( my choice would have been yellow, but its going to be the wife's, and we all know not to disagree don't we ) it had to be hit in polyester, and it shows up all the flaws.

Some were obvious before I started rubbing but it is the only way of getting a finish ready for any dark colour.

Just a few more,





This is why I always like to block new panels, ideally in polyester, no new panel is perfect and ready to fit.

Excellent work, and really valuable stuff as I've got all of this to come in the next few weeks!

So, let me get the process right (correct me if I'm wrong!). First pass of epoxy primer followed by filler (P40 waterproof stuff or polyester?), followed by a second coat of epoxy primer to and another batch of polyester filling to sort out the remaining rippley bits.

I've always been somewhat wary of polyester fillers having taken a great plate of the stuff off my old door skin hiding a completely rusted out panel (lovely work though, no idea it was there before it fell off...)

Depends on your situation, If its long term then I have epoxied all the bare metal and then filled, means the bare metal is protected. You can fill quite safely on top of epoxy, well the ones I use. Should have said I do all the lead work first before any paint.

I then seal with another thin coat of epoxy if most of it has been rubbed off in the sanding process, use it as a sealer. If most of it is intact I would then spot seal/prime with it then apply the polyester.

I am real careful with the poly not to get it damp or wet, regardless of people saying you can wet flat, you can but then bake it dry. I wont take the chance so don't get it wet.

Once the poly is rubbed I coat it again with a grip and wet coat of epoxy sealer, only thin enough to seal the poly.

Undercoat and wet flat, then shiny bit.

Hope that helps explain, people will have different regimes, this is just the one that works best for me and given me the best trouble free results

Same process on this recent 5 year resto of mine

So hours of polyester rubbing, bits I missed and it was ready at last for some high build primer
I gave the areas broken thru to bare metal another coat of sealer, for a bit of added protection and better adhesion.
As you can imagine with all the edges the bulkhead needed a lot.

Then it was 1 grip and 3 full wet coats. Don't normally put that much on but I tend to be a little heavy handed on full restos when wet flatting so I needed the build to make sure.
A few areas of seam sealer to do and the top is ready for gloss.
I will get it on the rotisserie next and stone chip and paint the underside and then the inside, especially where you can see body colour. The majority of the inside may just get on wet coat as I intend to fit dyna mat or similar so I wont be wasting expensive top coat only just to get covered up.

David,
Twenty-five years ago I had my Spitfire painted. They did as you are suggesting and didn't use top coat on the areas which would subsequently be covered by the trim. It seems the colour coat isn't as good a sealer as the top coat. The colour only areas have suffered from rust much worse that the areas which got top coated.
                                                                                          Best of luck,
                                                                                          Paul

Hi Paul
There was a typo there from me, it should have said one coat, the inside and all areas have already had a couple of good coats of epoxy sealer, the areas that show will get a couple of coats of the final finish, but the floors etc where I'm going to use the sound deadening, dynamat etc will only get one application of top coat. Paint is so expensive now, don't want to waste it on a covered up area. Also the epoxy sealers are so good they would be good enough on their own under the sound proofing but it just a bit of belt and braces type.

That's a nice long term ownership of your car, 25 years.

Cheers

David

Progress has been a bit slow, got the tub back on the rotisserie and found quite a bit of stopping and minor making good under the sills and lower areas, I must learn to bend lower when doing work.

So that's all done and re-primed.

Put a good 3ltrs of stone chip underneath to give good protection, touching up any bare metal areas with epoxy first, and then the first colour coat.
So on with 2k colour, it is going to be the wife's and she refused point blank to drive it if it is yellow, and suggested a dark or midnight blue we did a few samples of earlier. I love yellow cars, she hates them, so we came to a happy compromise, Midnight Blue.

Thanks, the wife didn't tell you to say it looked great did she?   I still like yellow  

Yep, although I haven't driven the FB much I'm beginning to get the itch to do another, but banned until the GT6 and my bike is done.

Waiting for my little girl ( 23 ) to return from her world domination tour, just been traveling and in Australia now, she saw this and asked if I would do it for her years ago, trouble is she hasn't forgotten and keeps reminding me for when she gets home. Still at least I have an ally, so I might get a nod of approval.
