So I've just brought a 2 year old car which had a GTechnic ceramic treatment done when it was new. I've just given it a good clean and there are some small swirl marks. Can I detail this car as normal i.e. polish , wax etc? Or do I need to do things a bit different?
Depending on which coating was applied it could well be that the minor swirls you describe are in the coating layer so a gentle tickle with a machine polish should rectify. If Serum or Serum Light was applied a light finishing polish won't remove the coating.
