3M Wet or Dry Sandpaper 80 Grit 50 per box Available for delivery 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. The standard 9" x 11" sheets can be cut to size for the application. 3M™ Wetordry™ products are backed with a proprietary waterproof paper backing that supports both wet and dry applications. Delivers 10% smoother finish vs. conventional 3M sandpaper Use as part of the 3M Body Repair System
