I'm saving my aluminum beer cans for you - I'll expect a nice polished alloy 550 Spyder out of them. Years ago I had a '62 356 Knotchback Coupe. I bought all the lead, paddles, and insulating putty to try to lead in bottom of fenders and doors. A lesson would have helped. I gave up and used a silver aluminum looking bondo.
I bet there are some good U-tubes on it out there and Eastwood has the tools.
Watching those guys work with the English wheel and shrinking/stretching hammers shows real skills. New Wheeler-Dealers had Ant (I do miss Ed!) do rust repair pieces for an old Saab 96.
