Our 3M™ Trizact™ Hookit™ foam abrasive sheet 443SA features a foam backing that provides support and conformability for removing fine grade (P1500 - P2500) swirl marks and scratches - ideal for painted surfaces where buffing is difficult. Micro-replicated 3D mineral abrasive structures are distributed uniformly across the surface and wear evenly for consistent finishes and longer sheet life.
