How to Repair Small Dents on Car Metal Panels?

If it's the front or rear bumper, which is usually made of plastic, the restoration is relatively easier. Pour hot water over the dented area of the bumper to heat it up. Once it reaches a certain temperature, it will soften. At this point, you need to strike while the iron is hot by pushing from inside the engine compartment outward until the dent is restored. If the dent is on the body's waistline or is a sharp crease, you will need to go to a 4S shop or auto repair shop for metal sheet repair. Here is an introduction to dent repair techniques: 1. Auto repair shops have a technique called dent repair, also known as light metal sheet repair. However, dent repair techniques are quite similar to DIY tool repairs. Both methods involve using suction cups to pull out the dented area, then inserting a hook behind the dent to slowly push it out, and finally using a rubber hammer to smooth out the protruding parts. 2. Door dent repair can save money and time, but not all dents can be repaired. As long as the paint surface is not peeling or chipped, and the dent is not too deep, the repair is relatively straightforward.
A few days ago, a small dent was made on my car door by a flying pebble, so I tried fixing it myself with a hairdryer. Set the hairdryer to the hottest setting and blow hot air directly onto the dent for about 2-3 minutes—this slightly softens the metal. Then quickly place a plunger over the center of the dent and pull firmly outward with steady pressure. When you hear a 'pop' sound, it’s almost done. Once the metal cools, the dent should mostly flatten out. Finally, polish the surface with toothpaste to make it nearly invisible. This method works best for coin-sized dents where the paint isn’t cracked. I’ve fixed three dents this way and saved a lot of money. Just remember to do it in the shade—direct sunlight can overheat the metal and make the repair trickier.
