Permanent marker in the hands of vandals means a big, annoying mess. If you have Sharpie marks on the roof of your car, chances are you've been targeted by a vandal, although this is, of course, not the only way marks can happen. No matter the origin of the marks, the solution is the same. Before you make the trip to the car dealer or an auto shop, take a look inside your bathroom or cupboards. It is there that you may find all you need to get rid of these marks on your roof. It will take a little time (but not much) and work, but it can be done.
Pour water into a clean bucket for your rinse water. If you have a garden hose available, you can just use that instead.
Spray hairspray or put rubbing alcohol liberally on the permanent marker marks. If there are several marks, or the marks are large, start with only one section at a time--otherwise the hairspray or alcohol on other areas will dry before you get to them.
Rub the Sharpie marks with a soft cloth. Apply more hairspray or rubbing alcohol if the mark isn't coming off easily. Turn the towel to the clean side each time.
Dip a clean cloth in the bucket of water. Rinse the alcohol or hairspray off the car. These products should not damage the finish, but could cause spotting if allowed to remain without rinsing.
Dry the finished area with a clean towel. Move on to the next area needing to be cleaned.
