I need new pads for paint correction , polish and wax. I also need help with the colors , which one to use and for what purpose? I'm using a Porter Cable DA machine. I have two cars that I plan to work on. Who have the best price, and are there any discount coupons out there? Been using the Meg's line of pads so hope fully this is a step up. I need something that is equal to Meg's Burgundy line for the paint correction phase.
