Can you repair paint damage on car?
The only way to fix this is to have the area sanded down and resprayed, either at a body shop or by a mobile spray paint service. This can be quite expensive, especially if the damage is all over.
How can I fix my car paint myself?
Unless the dent or scrape is very minor (and therefore very cheap to fix), older and less-valuable vehicles probably won't gain much value from a repair. You're often better off just keeping your money and living with the scrape and the knowledge that your car is a little less perfect than it was yesterday.
