Any one have any experience with using Spinergy Pads (Bridgepoint) for polishing stone? I have a set of the 5" pads for doing counter tops and showers and such. I have been using a hand polisher that has a low setting of 1500rpm. The Spinergy pads only call for the speed of a low speed floor machine, so around 350rpm. They seem to work, but not that well, and I'm thinking it is because my rpm is way too fast. Anyone have any advice for a machine?
