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. Microreplicated 3-D mineral abrasive structures are distributed uniformly across the surface and wear evenly for consistent finishes and longer sheet life.
