So, I should glue on a replacement door panel, and I would be better off welding the rest of the body mods?? To clarify, I am talking some extensive quarter panel and rear end mods on my Ranchero. Any seam that will require filler should be welded because of the different rates of expansion, is that correct?? Hey Streets, if I TIG the panel on, is lead ok over that too??? I quit body work many years ago, but am forced back into it because I can't find anyone to do the work the way I want it done. I guess this is why we are all hot rodders in the first place, huh ?? I really appreciate the input guys, I have a lot of catching up to do on the new body procedures. Thanks much for sharing your knowledge and experience.
