I also buy aluminum oxide rolls and use the 1" wide in about 8-10" long strips in the various grades and use WD40 to lubricate and see saw the sides of the pad that is at its final state. this smooths the rubber and the base. If you want you can use a piece of wood or tongue depressor to back it as needed
