If you have smeared gum on your car paint, there are a few things you can do to remove it. The first is to use a hairdryer to dry the area completely. This will remove any adhesive that may be left on the paint. The second is to use a vacuum cleaner and bucket to suck the gum up into the vacuum cleaner. Be sure to turn off the vacuum cleaner before sucking up all of the gum. Finally, use a clean cloth or paper towel to dry the area completely and remove any remaining adhesive.
