Well, I'm in the process of removing all the old body filler on my '72 SB and cutting all the rust holes out down to good metal so I can weld new pieces over the holes in the body and I'm confronted with the follow questions:
1) Should I treat all the rust underneath the body and frame before welding all the patches? (Seems to me I can get to more of the underside and hidden areas by treating them before patching all the holes)If so:
A) What is the best treatment for the rust? I've been told POR 15, Rustoleum Rust Reformer, Mar-Hyde and RustMort are all good products. B) I'm going to have the body media blasted after the patching, should I spray a primer shot over the patches as soon as I have them finished to stop any rusting or does it not matter?
Thanks in advance. H-S-F
