I'm interested to know who makes the buffer? For true "cut," a rotary is the way to go, but at the cost of needing a learning curve to use the rotary effectively and safely. Oh, and, clay before you polish to remove the contaminant in the clearcoat. This will help reduce the dirt grabbed by the pad that you get. Ever notice when you wax your car your pad turns black? That is what a clay bar helps remove.
