Our 3M™ Trizact™ Hookit™ Foam Abrasive Disc removes fine sand scratches on painted surfaces to reduce the amount of time spent compounding. Three-dimensional mineral abrasive structures are distributed uniformly across the disc surface and wear evenly for consistent finishes, longer disc life and reduced material costs. Foam backed discs are part of the 3M™ Perfect-It™ Paint Finishing System.
