Most people figure polishing is all that is needed to remove the roughness you can feel with your fingertips and clean the paint to get it ready for waxing, but polishing is unnecessary unless you are removing a scratch. You may only need to clean the paint to get it ready for waxing. Griot's Garage's clay is a pliable bar, and its sticky nature enables the clay to pick up and hold onto the contaminant as it glides across the surface. To enable the clay bar to glide across the surface, Griot's recommends Speed Shine be used as a lubricant. The Griot's Garage clay is bright yellow so it's easy to see exactly what's coming off of your paint. As the bar gets dirty, just knead it a bit and flatten it out into another fresh patty. Unlike other cleaners and polishes, no buffing or hard circular motions are necessary. Follow up with a paint sealant or one of Griot's famous waxes. One large, 8 ounce, 226-gram bar cleans about 7 vehicles, depending on the amount of contamination. Use the clay bar each time you wax and/or polish your vehicle for a smooth perfect finish every time!
