Bumpers are the first line of defense to your automobile, in case of an accident or a collision. So naturally, they're bound to get hit and buggered more, in comparison to other parts of your car. You can always replace the bumper panel, however, many people cover the bumper with a 'tough-to-remove' bumper sticker, which conveniently hides the damages. For fixing the bumper, the common procedure includes sanding, grinding, sculpting, and painting.
