I dont have a machine to polish yet and I am looking into getting one so I still have questions. One of them being how often can I polish my car? i know it depends on each car since the elements and paint will always be different. but I know when you polish with a machine you are actually taking a very thin layer of clearcoat off... So if i was to polish by machine 3 times a year would that be too many? how many times could I polish before risking taking most of all the clearcoat off? Thanks
