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 inch x 9 inch 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.
