I had the same problem myself mate, I owned the old Revs Escort and as much as it looked mint it was ready for the bin after being blasted, I have no idea why the built a car they were giving away in a magazine with such a fu**ed shell, it even had cunt written in weld under the fuel tank

I replaced that with a freshly built Grp 4 shell that needed a few bits finishing and that went to SPL to be dipped, it then turned out the reason it has had 2 new inner wings was possibly a accident as the A pillar had been mullered and repaired, not a massive issue as I was so far into spending that I just had the whole thing done and finished but never believe a car is mint, filler and paint cover up a LOT of stuff
