Just a quick question. I just purchased some RMG and will be tracking down the UPS driver every day until it arrives. My question is do I need to prep the car at all before using this? The car has P21S wax on it and the finish is in excellent condition. Sooo, my plan is to just hit the car with RMG with the PC and them cover it with Pinnacle Souveran wax. It is my understanding based on the discription of RMG it does have some mild cleaning agents which makes me believe that I don't have to repolish the finish before RMG. THANKS again.
