3M™ Wetordry™ Abrasive Sheet 401Q is an abrasive sheet designed for sanding applications that require a fine grit and a light touch, such as auto body wet sanding and paint finishing. It combines a durable, waterproof A-weight paper backing and 3M's fast-cutting silicon carbide mineral for consistent scratch patterns, making for easier buffing.
Use the 3M™ Wetordry™ Abrasive Sheet 401Q for leveling dust nibs, smoothing orange peel, and light sanding on surfaces like clear coat and gelcoat with reduced risk of burn through. It is durable yet flexible, with a sharp cut that leaves a refined finish. The durable paper backing helps create consistent patterns that are easily buffed out.
The silicon carbide grain is available in a variety of grades for a full range of non-aggressive sanding and polishing jobs on clear coat, gelcoat, plastic and metal, including areas that require hand compounding and for sanding dark colored paints. It comes in a range of sizes to reduce tearing for specific tasks.
3M™ Wetordry™ products are backed with a durable waterproof paper backing that supports wet and dry applications. Lighter weight than cloth and smooth rather than textured, the paper backing is preferable for lighter applications such as finishing and paint prep. Many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment.
