Abralon Abralon - (P GRIT grading system) foam backed disks! Great for high luster on exotics, man made materials and anywhere a super fine finish is required. (Sand your lacquer before buffing!) Combines benefits of abrasive cloth and non-woven products. Constructed with a fabric face, foam center, and a grip backing. Abrasive grains are bonded evenly to the fabric face. Openings in the fabric allow water, solvent and air to flow freely around the abrasive. Works especially well when sanding contoured surfaces, corners and sharp edges. Open cell design holds large amounts of water or solvent for lubrication and cooling. Foam center also provides for even surface pressure that helps eliminate finger marks when hand sanding. These disks are available in 2" and 3" sizes 360, 500, 1000, 2000, 4000 Grits and the grit number is stamped on the back
