I'm working on the cab of my stude and there is a seam all the way across the back of the cab above the window. I think it's filled with lead, it is kind of rough so I want to do something with it. I have some fiberglass reinforced filler I was thinking of using, is that a good idea?.
I also have some lead filler at the top edge of the doors right where the gutter ends and it is cracked. Is it better to try to heat it and reform it or just get rid of it and use filler?
