11. With the Powerball chuck into a Makita drill motor set at about 1400rpm, I started the polishing process. You can apply the polish to the ball or on the wheels, I chose to load up the Powerball and then smear it around. I took a while for the shine to show back up, but the Powerball held up like a champ. I kept the ball pretty wet with polish so it slung stuff everywhere, but it was worth it.
