In a rear-end collision, the first thing to be injured is the front and rear bumpers. The rear bumper of the car is dented. If the original paint is not scratched, we can use the following methods to repair it:

　　1. Repair with hot water

　　Hot water is the most common method for repairing car bumper dents. Because the bumper is made of plastic, it will soften when heated, so just pour hot water on the bumper dent and use a toilet spatula to suction it. Generally dents are no problem.

　　2. Push it back with your hands

　　If there is a small dent in the car's bumper, you can also try to remove a screw from the car, put your hand into the bumper, and push it back to push the bumper back; however, this method can only be used to repair minor dents. If the dent is severe, you may not be able to lift it.

　　3. Dent repair tools

　　Although the above methods can repair dents, they are only small dents. In many cases, the expansion of hot water is not strong enough to repair the dent, so special dent repair tools are used, which are also commonly used in auto repair shops.

　　It should be noted that if the bumper is severely dented, or there is a reversing image or radar in the dented position, or the paint is knocked off and needs to be repainted, it is not recommended to repair it by yourself.
