I don't have a PC. All I have right now is a craftsman buffer I bought from sears. It's 10" so it's really clumsy and difficult to use. I used it two weeks ago to apply the paint polish and the sealer/glaze. I applied the wax by hand but buffed it off using microfiber pads on my craftsman. Then I did a final buff by hand using some Mother's Showtime QD.
I use a combination of Armor All tire foam and Armor All
Tire Shine Gel on my tires. I like the cleaning power of the foam, but it doesn't look that great. I use it to clean the tires and give the Gel a clean tire to adhere to. The result is a longer lasting, shinier tire.
