Getting the Most From the 3M™ Finesse-it™ System Used together with 3M™ Finesse-it™ Polishes and Foam Buffing Pads (sold separately), the buffer's dual action feature with a 3/8" (10 mm) orbit provides a uniform, haze-free and professional-looking paint finish. The system enables paint shops to save time and money by repairing defects rather than repainting. It may also eliminate the need for a secondary polisher. Our 3M™ Random Orbital Buffer 28392 was carefully engineered to optimize the performance of 3M™ Disc Pads and 3M™ Foam Buffing Pads for first-rate results. Use only with a foam buffing pad and never a wool pad.Not exclusive to paint shops, 3M™ Buffers are an excellent choice for a variety of repairs on different substrates across a wide range of industries – from paint and clear coat to lacquered wood, solid surface and acrylic. Ergonomic Features Provide Maximum ComfortFor greater operator comfort, the tool grip features patented 3M™ Gripping Material to provide a secure hold and enhanced control with less hand pressure, even if polish finds its way onto the grip. Additionally, the gripping material helps reduce vibration for greater comfort. To reduce stress on the wrist and hand, the tool is designed with an extended curved wrist rest, which provides additional leverage as well. The tool also has a built-in muffler and rear exhaust.
