Shorten or eliminate the compounding stage from your paint finishing process by using 8000-grade 3M Trizact Hookit Foam Abrasive Sheets before you polish. Used to refine 3000-grade or finer sand scratches, they leave a surface so smooth you can forget the compound and start polishing. They're the industry's first 8000-grade abrasives — built with a 3M technology nobody else has.Meet paint finishing's first 8000-grade abrasives – 3M Trizact Hookit Foam Abrasive Sheets. They allow body shop technicians to use a lighter sander instead of a heavier polisher for removing 3000-grade and finer sand scratches. These long-lasting sheets are used to refine very fine sand scratches, which were traditionally refined with compound and a pad. They leave a smooth surface and reduce the risk of swirl marks, burn through, and other defects. In many cases, the technician can eliminate compounding and begin polishing. 3M Trizact abrasives deliver long life and a consistent finish thanks to an exclusive 3M construction. These sheets have unique three-dimensional abrasive structures that expose fresh, sharp mineral as they wear. For best results, we recommend using 3M Trizact Abrasives with one of our 3M Perfect-It Paint Finishing systems. However, they can be used before any brand's pads and liquids.
