Nah it doesnt take any proper protection off, ie wax or sealant. If you are only polishing its gonna come off if you do or dont jet wash as you arent sealing it to the paint.
Gets 3 coats of Autoglym Carnuba Wax 3 times a year, since I haven't done it for May it's due again, but it's hard getting a full dry day to do all the polishing and waxing by hand.
