I have not used the Mother's polishing tool but rather a simple home made device. Simply take any generic ShamWow cloths and cut them into 6" squares, use an awl to poke a hole in the center of the cut cloths and mount them onto a threaded rod with a couple of fender washers. I usually stack between 10 and 15 squares. These last a long time and can be washed if you like. It doesn't hurt to take the cloths off and reverse them for more even wear. I use the same technique with scotch brite pads to remove rust or paint from metal or wood.
Works good, last a long time and very reasonable.
