Super-fine abrasives that work dry: Tolecut is the smartest, most advanced system for removing surface imperfections. High-tech abrasives on a urethane backing cut shallow and clean, for the kind of results that used to require wet-sanding. Working dry means you can clearly see your progress. No water and rags—just scuff, buff and go. The long-lasting sanding squares are adhesive-backed for use with Toleblock sanding blocks. Toleblocks are firm, but not rock-hard: the perfect “give” for spot-sanding.
