A couple months ago I decided to pick up one of those $30 Harbor Freight rotary buffer/polishers. I decided yesterday to pull it out and put it to the test on my wife's car. She hit the side of the garage while pulling in about a year ago, scraping the passenger rear door molding and quarter panel. I've used an orbital plenty of times but these rotary's are a whole new monster. Below are the before and after pictures...I'm impressed for my first time...I also tried really hard to rub out the rust hole at the bottom of the door, but I just couldn't find the right compound/pad combination.
