Wetordry 2014Click To Copy 0 431Q Series Paper Sheet, 9 in W x 11 in L, 180 Grit, Very Fine Grade, Black

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. These versatile sheets are ideal on surfaces that tend to generate a lot of dust, such as paint and primer; and can also be used dry for finishing metal and gel coats. In the marine industry they are used for sanding old finishes, fine feather edging and surface work.
