This premium 320 grit third sheet of 3M™ Performance Sandpaper is constructed with a high quality aluminum oxide mineral which is blended with a ceramic mineral for superior performance. Designed for hand sanding, each 3-2/3” x 9” third sheet can be easily attached to and used on a sanding block. During Stage 3 of the 3M Body Repair System use 320 grit sandpaper to shape and sand glaze or spot putty prior to priming. After sanding with 320 grit sandpaper, apply primer per manufacturer’s recommendations. Then, use 320 grit sandpaper during Stage 4 to sand primer. Follow this step by sanding primer with 400 grit sandpaper to refine 320 grit scratches. This 320 grit product is made with aluminum oxide, a tough and versatile mineral abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate, clog resistance and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide is highly effective for sanding and finishing. When a project necessitates exceptional results, look to 3M™ Performance Sandpaper for your surface finishing solutions.
