Product Description

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.

  • Convenient sheet can be used wet or dry on paint, primer, gel coat and metal.
  • Silicon carbide mineral is 3M's fastest-cutting abrasive for a superior finish.
  • Waterproof backing supports wet applications for decreased loading and a faster cut.
