431Q Coated Sanding Sheet, 11 IN L x 9 IN W, 180 Grit, Very Fine Gr

3M™ Wetordry™ paper sheet 431Q features extra fast cutting silicon carbide on a strong C-weight, waterproof paper backing to provide superior finishing for both wet and dry applications on a variety of substrates, including paint primer, gel coat, metal and wood. Used dry or with water, 3M™ Wetordry™ paper sheets enable the user to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust, while producing a faster cut at the same time.
