You'll see long abrasive life and consistent finishes thanks to the patented 3M Trizact Abrasives. They are built with our unique three-dimensional structures which wear to reveal fresh, sharp abrasive mineral. 3M Trizact Hookit Foam Abrasive Disc 3000 can reduce the risk of heavy swirl marks which can be introduced during aggressive compounding. Used damp, they deliver the anti-loading benefits of wet sanding without the productivity-reducing hydroplaning which can happen when power sanding on overly-wet surfaces. The foam backing provides plenty of control and consistent contact with the surface - great for preserving orange peel. Can be used with a soft interface pad for added conformability over curved surfaces. When used with other 3M Trizact abrasives and one of the 3M Perfect-It Paint Finishing Processes, they can reduce overall polishing time. 3M Trizact Hookit 3000-grade Foam Abrasive Discs are available in 3-, 5-, and 6-inch diameter discs and 2 3/4 x 5 1/2-inch sheets.
