Agree with the PC 7424 with the 6.5 in pad kit. I use Griots orange pads for application and pre-polish, grey for polish application. I find 3m Perfect-it to work about the best. Wax, I try to find the highest % Carnuba content without getting ridiculous, P21s is a good general purpose example. Certainly you can spend thousands for Brazillion carnuba......I would like to see a side by side comp before making a judgment.
Example of PC.
