So I have a Harbor Freight DA; I've bought a backer plate for it and I've changed out the internal gear lube to get it ready to put to my car. I've got a Orange, a yellow, and a black Buff and Shine brand pads for it too. I'll be using a Mequire's Ultimate Compound, Ultimate Polish, and Ultimate Liquid Wax on my black car. What speeds should I be using on the Harbor Freight unit for each of the stages? Thank you!
