When compounding, if the speed is too high, the aggregate gets used up faster and loses its ability to remove oxidation. Stick to 2,500 to 3,200 orbits per minute (OBM). Waxing and polishing can be accomplished at between 3,900 and 4,600 OBM. Higher speeds are useful when removing paint defects and swirls. Wax and compound makers often specify a machine speed, so check the label of the product you're using.
