Wash the vehicle thoroughly before use. Unwrap the clay and knead it lightly to flatten it. Use with Glass Detailer (336505) as a lubricant, diluted 1:10, is recommended. Rub the surfaces lightly with horizontal movements to remove the deposits. Wipe with a clean microfibre cloth and check whether you have achieved the desired result. If the deposits have not been removed, repeat the process. During use, knead the clay so that you always work with a clean side on the surface. After use, wash the clay with water, dry it and store it in its plastic packaging until next use. Do not store it wet. The clay is not suitable for matt paints and matt films.
