Regardless of how clean you think your paint is, there are still contaminants stuck on the paint that you need to remove before waxing or polishing your paint. Paint Cleaning Clay leaves behind an ultra-smooth surface that will make your wax adhere better and last longer, too. It also makes the wax much easier remove, reducing your "elbow grease" substantially. Clay is safe for all paint and also works great on glass to get it squeaky clean. To use, just remove the clay from the wrapper, spray the paint's surface with Speed Shine® (acts as a lubricating fluid), and rub the clay back and forth until there is no drag. This means your paint is clean! Unlike other cleaners and polishes, no buffing or hard circular motions are necessary. Takes literally one fourth the time as it would using paint cleaner! Follow up with Best of Show Wax® and your paint will look stunning! The large 8 ounce bar cleans about 7 vehicles, depending on the amount of contamination your surface is covered with. Can be used by hand or with the Griots Random Orbit polisher with the Paint Clay Pad (or with the adjustable pad holder). Priced individually
