3M Wetordry™ 401Q Aluminum Oxide/Silicon Carbide Sanding Sheet

3M™ Wetordry™ abrasive sheet 401Q is designed for sanding applications that require a fine grit and a light touch, such as auto-body wet sanding and paint finishing. It combines our durable, waterproof A-weight paper backing and our fast-cutting silicon carbide mineral for consistent scratch patterns, making for easier buffing. And a range of grades up to 3000 grit allows for superior results.
