Had a couple of pieces off the 74 blasted & am doing my rust repairs on a fender, headlight bucket is out, once the welding is done I want to por15 the rear side & whatever framing I can get to & epoxy prime the outer skin. Trying to avoid some of the problems I had on the 73.
Now there's a residue from the blasting, a grey tint to all the metal, tried a few different cleaners & metal preps I have laying around & they barly remove any of the gray "stuff" for lack a the proper term.
sanding gets it to raw metal.
long winded for a simple question, do I need to remove all that stuff or do I just paint over it? Thanks,Rich.
