I just bought a Griot G9 and want to start learning how to machine polish my car - an Agate Gray Porsche. The car is in reasonably good shape, with some minor swirls and scratches, and at least in the short term, I still plan on having any major paint corrections done by a professional, and I would just do some refreshing in between. I was thinking that I would start with a one step polish and spray wax to keep things simple. Anyone have any suggestions on a polish and wax to start with?
