Our 3M Trizact Hookit Clear Coat Sanding Abrasive Disc 471LA is ideal for spot repairs, including leveling dust nibs and orange peel, before sand scratch removal. Microreplicated 3-D mineral abrasive structures are distributed uniformly across the disc surface and wear evenly for consistent repair and longer disc life. Film-backed discs are part of the 3M Perfect-It Paint Finishing System.
