The surface of your car should be clean before you start detailing. Obviously, you want to wash the car and get the major dirt and road debris off the car. The next step is to get the dirt and contaminants that are bonded into the clear coat off the surface. So, the first thing you should do to this panel after an initial wash is using a clay bar over the paint. What that’s going to do is pull out all the contaminants that are in the paint so that when we buff the entire panel we’re buffing the paint and not just pushing the contaminants around.
