Just used it tonight. Gave it a wet sand first and washed it down with some concentrated acid and gave it a buff with stuff picked up from Peterbuilt in town. Was amazingly easy
Just used the small Powerball on my 09 D8 yesterday and it worked great just watch out for the boards it will shread it fast. Just know one thing once you start you can't stop! I was just going to do a little next thing I know 3 hours and a bunch of these had gone by
