Begin slowly and move the buffer over a small area (about 2 feet by 2 feet) until the area is covered with polish or compound.
Gradually increase the speed while moving the buffer over the area. Start horizontally, being sure to go over the entire area. Go back over the area, in vertical passes, to ensure the entire area is buffed. When the area starts to look shiny, increase the speed setting to high and go over the area again, with light pressure, to finish.
