I purchased a steel tub with significant body filler everywhere. By significant I mean almost 1/2" I'm some areas and 1/
4" in rear. I had the inside and bottom of the tub blasted and the bottom appears to be in pretty good shape. I began to remove the bondo on the rear quarter - first with heat gun and chisel, 2nd with 80grit. Good news is the metal seems good. No rust. Bad news is it appears my removal technique seems to be a bit aggressive. See pic below with the steel and some gouges from the chisel. If the tub is good, I'd like to use as little bondo as possible. Are these blemishes in the steel something that can be sanded out, or filled in with high build primer, or does it look like I'm going to have to skim the entire tub with filler.
Thanks!
