We use the Porter Cable 7424XP, Amazon.com: Porter-Cable 7424XP 6-Inch Variable-Speed Polisher: Home Improvement
and Meguiar's Marine wax, Amazon.com: Meguiar's M6332 Flagship Premium Marine Wax - 32 oz.: Automotive
Very happy with both purchases, this polisher is pretty much the industry standard. Most detail shops use it or the Griot's Garage polisher. Since we have three vehicles plus our 831RKSS, I could easily justify spending the money on the Porter Cable. Between the Excursion and TT, we have enough paint real estate to justify it alone. I use the polisher and my wife comes behind me to wipe the wax off. Doesn't take long at all and leaves excellent shine and protection.
