I have a new (2months old) facelifted 203 with nano technology coating. When I first got the car I noticed that it was lightly scratched all over (straight line scrathes) which were only visible in sunlight or the lights in my garage. I took the car back to the main dealer who re-polished the car which looked fine when I collected it. I washed it and gave it a quick polish with mercedes brand items and it now looks even worse the fine scratches look really bad but again only in sunlight or garage lights. The colour is Jasper blue. I would be interested if anyone else has had similar problems - any advice?
