3M™ Green Corps™ Sanding Abrasive File Belt strips away paint, rust and welds in hard-to-reach locations on automotive bodies. We chose aluminum oxide abrasive because it works quickly in stripping away paint down to bare metal, plastic or fiberglass, giving automotive paint technicians a clean surface for restoration work. This automotive paint stripping belt works with 3M™ File Belt Sander 28366 and other belt tools. These file belts can quickly remove stock in tight areas while allowing technicians increased control over other methods of structural disassembly. A grinding aid allows for cooler grinding, which reduces heat on the surface of metal substrates to preserve structural integrity. Aluminum oxide is a popular abrasive among industrial professionals because of its fast cut-rate and long life. This mineral makes 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 fast cut-rate, hardness, strength, and low heat retention, it is widely used in grinding applications. The abrasive has been resin bonded for heat resistance.
