I just purchased a 00 Renault Scenic for our second car. Great car in good condition with alloys, a/c, electric windows, etc. great value and I could not walk away. The only downside with it is that on the paintwork, which is a metallic silver, there are blemishes caused by little handprints. I think they might have bben caused by vinegar or grease on the hands of the previous owners children. Is there anything I can do to get rid of these? they do not rub off obvioulsy enough and it is like if they have taken the metallic out of the paint if you can get my drift. Any ideas would be most welcome.
