I know shrinking metal is kind of a mystery to some folks. Shrinking 18 or 19 guage metal on a Model A is one thing, doing it on todays flimsy-assed metal is yet another...but effective if careful. The following pics show a car I am working on....quarter panels were both buckled pretty bad from pulling the rear out some on a frame machine. If the panel is removable, I just replace it...cheaper...but quarter panels are a pain to change. I have used my stud gun to heat small spots then immediately cool the spot with a wet washcloth ( I have a shrinking tip for the gun). It works like a charm. In this case, the result of using studs and shrinking the panel is a straight panel needing only some thin coat of glaze putty to finish the repair. Using a torch or shrinking disk on an A you can make an amazing difference in the panel. Patience is necessary of course.....
I was shrinking metal before shrinking was cool....
