Shorten or eliminate the compounding stage from your paint finishing process by using 8000-grade 3M™ Trizact™ Hookit™ Foam Abrasive Discs before you polish. Used to refine 3000-grade or finer sand scratches, they leave a surface so smooth you can forget compounding and start polishing. They’re the industry’s first 8000-grade abrasives — built with a unique patented 3M technology.
