While wheel is rotation, apply the compound in a semi-circle motion to the edge. Light pressure and 2 to 3 passes across the face of the buff is all that is required. If the face of the buff becomes hard or is leaving streaks on the part, the buff needs to be raked. Raking the buff will also keep the buff balanced. If a black deposit of compound develops on the part, the part is not hot enough. The part should be hot enough that you can not touch the area that you are buffing with your bare hands. Cotton gloves are necessary to hold the hot parts.
