Yes I know the painter will polish to make the paint 'even' or so to speak. It shows that it is already safe to polish. After they polish they will just wax(the hardworking painters la...lazy ones after polish cabut edy) But most of the time when I see freshly painted cars or brand new cars(both my parents car from Auto Bavaria and my old Civic), the paint surface is full of swirl marks! Polish or not...same one 100% swirl free is impossible judging by Malaysia's ultra frenly weather but I've seen a few cars coming out from auto detailers like Carnauba Autospa, their paint surface are free from swirls! If got also maybe like a few only under intense light. So my point is find someone who will do the job properly. Carnauba, Harry Bright, Imola Autospa, Auto Detailer are very very good in eliminating swirls. 2 thumbs up from me! Yes polishing will strip a BIT of the clear coat but I guess you have heard about different grades of polish rite? Dun simply assume that if polish, the paint will strip off. Relax!
