3M buffers PNs 28333 and 28769 are designed for use in automotive manufacturing (AOEM) paint shop applications for buffing or polishing medium-size defects on clear coat, powder coat, acrylic, solid surface and polyurethane. Both tools feature a powerful yet quiet 0.26 hp precision balanced air powered motor and numerous ergonomic features for expert handling and comfort during prolonged use. Used together with 3M Finesse-it polishes and foam buffing pads (sold separately), the buffer's 1/2 in (12 mm) random orbit makes it nearly impossible to burn the paint and 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 subsequent polishing step. The 3 in 3M random orbital buffers 28333 and 28769 are 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 to acrylic. For greater operator comfort, the tool grips feature patented 3M gripping Material to reduce user fatigue, providing 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. The tools also have a built-in muffler and rear exhaust. These features enable professional performance with less operator effort and fatigue. The included 3M Hookit disc pad has a low profile to accommodate a 3M Finesse-it foam buffing pad or other hook and loop buffing pad (sold separately) and provides a secure hook and loop attachment for the pad. Constructed from premium, industrial quality materials and featuring a riveted fiberglass and steel hub with molded urethane, the disc pad's durability and precise construction is the ideal complement to the industrial-level performance of the buffers 28333 and 28769. Use the tool only with foam pads, never with wool. Professional results are optimized with the use of a very fine polish such as 3M Finesse-it polish.
