Buffer for polishing.
I got this one from Canadian Tire made by Meguiar's and it just attaches to your drill.

I used it on my Toyata Highlander and it works awesome. Read the reviews on CanadianTire.com and Amazon.com
It's on sale this week for 25% off too.
You can also buy the different colour pads for different wax applications (glaze and prewax cleaner) when they are on sale 25% off too.
Great item for the money.
