This pad is the first step in the Rupes Big Foot Polishing System. The Blue Coarse Foam Pad is very aggressive in its construction and was designed to be used with a cutting compound. This pad is capable of removing up to 1500 grit sanding marks on fresh paint. Swirls, light scratches, water spots and other paint imperfections will be effortlessly removed with this pad. Always follow this pad with a less aggressive pad/polish combination to maximize gloss and surface smoothness.
