3M Scotch-Brite 7442 Ultra Fine Scuff Sponge
Scotch-Brite Ultra Fine Scuff Sponge is a great hand-held cleaning agent designed to help with intermediate scuffing applications. Under the microscope, an ultra-fine grade reveals tiny, small, densely-packed mineral that counters the more aggressive cut of a denser grade abrasive. The fine grade produces a finer finish that will not compromise the geometry of the part by gouging or marring it.
