Re: 85 GMC dirt cheap refresh
Did some block sanding on the cab, then cleaned up the floor. I removed all of the old seam sealer and put some new stuff in there, removed the surface rust that was on the right floor, and went over my welds with some waterproof fiberglass filler incase there were any pin holes that I missed. After that was dry I sanded the floor down with some 80 grit, and shot a couple of heavy coats of dupont corlar high solids epoxy mastic.
