The 3M Stikit Finishing Film Disc 01319 is designed for use in scuff sanding before painting, as well as to remove runs, dust nibs, and excess orange peel from paint and gel coat prior to compounding. This disc allows for machine sanding versus hand sanding prior to using very aggressive compounds. This product cuts fast, lasts long, resists loading, and leaves a consistent finish. Suggested 3M Backup Pad PN05546, 3M Backup Pad PN05556 or 3M Backup Pad PN05576. Can be used with 3M Random Orbital Sanders.
