So, figuring on soon owning 3 black cars, I thought it was about time I got a real buffer. DA from Meguiars, since I use their pads and stuff. as suggested by a friend who does this for a living. I think it turned out well for my first go-round. 60,000 on the Tesla and 135,000 on the Tahoe. 6 hours spent on each this weekend. Wash, Dry, Claybar, correct, wax. My everything hurts.
