Corded drill, mothers powerball and blue magic polish on the wheels.
The blue magic has more cut that most any polish out there. So if they are bad, this will save you some time. I have used 18v dewalt cordless drills on these bigger wheels before and the batteries just do not last. Even when using 3 batteries.
Polished the alcoa wheels on a GMC Topkick
I apply the blue magic thick with an old MF. Start out with the drill on low speed to work the product in, then increase the speed as you go. I do about 20% of each wheel at a time.
