For the application must be said that you look breaks from the dough slightly and the Fahrzeuug cleans course previously. Then I have the car sprayed wet and then with the Meguiars Ultimate Quik eingsprüht Detailer Quick Paint cleaner the surfaces and then (flattened Handball large) rubbed with clay. This piece can then knead again and re-use. Only when the cleaning power decreases take another piece of clay.
