Hey Genic.... I seem to remember you back in the "old" days. Was your Coupe the one parked on the side of the road outside Llandod?
No idea about the welding... a bit of stiffening in certain areas could be an idea. Perhaps under the sills, and the box section under the rear seat. Will add weight though. Hi mate , wasnt my coop, there used to be one the same colour as mine parked in newbridge but have not seen that around for a few years. had my coop 13 years now so was around in the old days.

Dip over blast for me. Blasting doesn't get inside the sills and other box section seams. Dipping isn't cheap though. Both courses and the zinc coating is around £1400 plus trailering the car there and back twice to have repairs / seam welding done in between. But it will last far longer this time round.

£1400 for the dipping process! I know we all spend too much on our coupes, but that plus a respray makes an expensive proposition.
You you will be preserving your shell for another 20 years or so and also find out how much rot you have or haven't got. My vote is for dipping and seam welding

My vote is for dipping and seam welding Very true, but what will the car be worth in the future. Having a family background in classic car restoration, unless you really love that coupe for some reason, budget has to come into it.

If we don't do stuff like this there won't be any left in the future. Or what will be left are just patchwork sheds needing total restoration at huge cost. The value isn't really going to change till there are hardly any left.

I have just read a book "The unfair advantage" by Mark Donahue. In he talks often about acid dipping bodyshells to cut wait on race cars. Indeed there was one car which had been so dipped the roof had buckled so they put a vinyl skin on it. The also acid dipped some engine blocks but they were lost and ended up in production cars. My guess would be that the advantage of wieght saving would be at the cost of a more fragile body restiffened with a cage. Could some unsprung wieght be lost by acid dipping?

The dipping removes all traces of sean sealant, sound proofing and of course rust. How much material removed from the steel is mostly down to the man operating the process.
I think they've gotten to the bottom of the horror stories. Where shells were not washed thoroughly after dipping. Or where the optional zinc dip wasnt carried out (to save money)
Or where a shell was sat too long berween.
I am definitely going to get my shell done this year. It will be stripped, dipped, repaired and stitch welded. Then lightly dipped again before a zinc coating applied and then fully resprayed inside and out and fully cavity waxed.
Its not going to be cheap but I want this car to last. I'll be fully covering the whole build in my project thread.
Also worth looking at is Dax's project thread. Great build.
