Tackle tough stuff like fallout, tree sap, water spots, bugs, road debris, and more from your vehicle's exterior surfaces, including paint, glass, chrome, and plastic. The FAST Surface Prep Mitt is designed for more stubborn, more plentiful amounts of embedded debris than Griot's Fine Surface Prep Mitt. Its unique diamond patterned polymer surface measures 5 1/2" x 7 1/2" and is seven times larger than a traditional 3" x 3" clay bar, delivering more efficiency per pass and ultra-fast contamination removal while lasting 10 times longer. Both efficiency and comfort are improved dramatically over traditional clay bars. Griot's useful mitt makes this essential step prior to paint correction, waxing, or sealing as easy as waving your hand.
