How to Repair Dents on Car Body?
2 Answers
Solutions for car body dents: 1. Metal Sheet Repair: This method can be used to repair both large and small dents. Although metal sheet repair is relatively expensive, it yields the best results. Car owners generally cannot perform metal sheet repairs themselves and need to visit an auto repair shop. 2. Using a Car Dent Repair Kit: The principle of a car dent repair kit is to use tools such as a hot glue gun and a bridge-type suction puller to attach a suction cup to the car body and then pull the dented area out using the principle of tension. Although it is simple to operate and can be done by oneself, the final repair quality is not as good as traditional metal sheet repair. 3. Pouring Hot Water to Repair: This method uses thermal expansion and contraction to restore the dent through elastic deformation. The operation is also very simple—just prepare a pot of boiling water in advance, pour it on the dented area, wait for it to heat up, and then push the dent back into place by hand.
I've repaired many car body dents, and it really depends on the severity of the dent. For small dings or minor dents, you can try the heat and stretch method yourself. Get a heat gun or hair dryer to warm up the dented area, soften the metal, and then use a specialized suction cup or tool to pull it out—simple and cost-effective. For moderate dents, you might need professional stretching rods or pry bars to gradually reshape the area. Don’t forget to clean the surrounding paint to avoid scratching it. For severe dents involving metal deformation, it’s best to take it to a body shop. They use machines for precise stretching, apply filler, sand it down, and finally repaint to restore the original look. Throughout the process, prioritize safety—wear gloves to protect your hands from burns and avoid damaging surrounding parts. Minor dents can be fixed in a day with DIY methods, but for complex cases, leave it to the experts, costing anywhere from a few hundred to several thousand yuan.
