The Mustang I'm working on had an inch long verticle crack in the quarter panel right at the rear edge of the back window. In order to weld it up, I melted away about an inch of the lead seam where the roof meets quarter.
My question is, can I use a filler to build this area up so that it blends into the lead? Also need to put some kind of filler on the lead to smooth out wire brush marks & scraper gouges. Any issues there?
I really don't want to end up having to melt out the entire lead seam & use filler in it's place.
