If you’re looking to take the first step into machine polishing the best machine you can start with is a dual action polisher. These are relatively low risk and due to the orbital rotation you are quite unlikely to damage the paint work unless you stand there on full power with the pad in one place for 5 minutes!

You can get outstanding results that are much improved over hand polishing, even as professionals we still use our dual action polishers for working on some aspects of a vehicle.
