Shurhold 3100 Dual Action Polisher. The design goal of Shurhold's Dual Action Polisher was to allow users to achieve the same high gloss, professional finish that the pros do with a rotary buffer/polisher, but in a unit that less-experienced, everyday users can operate with the same effectiveness. Traditional rotary polishers have a larger wheel spinning at a high RPM, which means the operator's technique is important as to avoid burns and swirls. The Shurhold polisher's dual-action, 6-inch oscillating head eliminates these issues and allows anyone to get the same great finish without burns or swirls. General detail maintenance like waxing and buffing can now be done in half the time, with half the effort and half the amount of product. Standout features include: the quick change pads with Velcro backing, the GFCI (ground fault circuit interrupter) that cuts off power to the unit should it become submerged or shorted by water, and the addition of a 20-foot power cord with no stubby pigtail. The National Marine Manufacturers Association (NMMA) liked this product so much that they awarded it top honors with an innovation award at the 2009 MAATS (The Marine Aftermarket Accessories Trade Show) in the category: Boat Care, Coatings, Chemicals and Maintenance Tools. This polisher comes with a canvas bag, PU quick-change Velcro backing plate, wrench, D handle, and a carbon brush. (Note: Pads are sold separately.)
