Any true paint correction begins with the right polisher. There are 2 types of polishers, the orbital and the random orbit. The orbital spins in one direction and is usually used for aggressive correction. Most commonly, body shops use the orbitals to polish out orange peel and fish eyes but you can also use them to put on final finishes. The random orbit adds and additional axis so the polisher spins and wobbles. This helps to minimize swirl marks and they usually build less heat. Most of the time, if you are looking for a machine that gives perfect paint correction results, you want to consider the random orbit polisher.
