What are the methods for repairing a dented car door?
3 Answers
If the paint on the dented area of the car door is not peeling or chipped, and the dent is not very deep, it can be repaired using professional tools to restore the body to its original condition as much as possible, without the need for panel beating and repainting. However, if the dent is large, it is advisable to take it to a repair shop or a 4S store, as attempting to repair it personally carries significant risks. Below are the relevant details: Repair method for shallow dents: You can purchase a dent repair tool kit. First, clean the dented area thoroughly. Then, load the special glue into the glue gun and plug it in to preheat for about 7 minutes. Next, select an appropriate pad—note that larger dents require larger pads, as larger pads provide greater traction. Apply the melted glue evenly onto the pad using the glue gun and quickly attach it to the dented area, pressing gently until the glue sets firmly. Align the hole in the center of the pull bridge with the firmly attached pad, screw the nut onto the pad's screw rod, and tighten it. Continue turning the nut until the dent is pulled out and leveled. After the repair is complete, remove the tools, spray alcohol on any residual glue on the car body, and finally clean it off with a scraper. Repair method for deep or large dents: It is recommended to go to a 4S store or a professional car detailing shop for repair, rather than attempting it yourself. This is because most car owners lack the professional skills required, and improper repairs can easily cause secondary damage. If you choose to repair it yourself, you must consider whether you have the necessary professional tools, how to proceed with the operation, and what to do if the repair fails, among other issues.
There are dents on the car door, and I've tried several methods myself. Initially, I used a suction cup tool to pull from the outside, which worked for shallow dents but had no effect on deeper ones. If not done carefully, it could even scratch the paint, so it's better not to mess with it. Heating with a hairdryer and then pushing hard also carries risks, as it can easily deform the metal. Later, I got smarter—using a specialized pull rod from the inside to slowly push small dents flat, but removing the interior trim is a hassle. Professional paintless dent repair (PDR) is the best choice, as technicians use tools to precisely push and press without damaging the paint, especially suitable for preserving the value of new cars. Remember, leaving dents unrepaired can lead to rust, so be mindful of surrounding obstacles when parking. Before choosing a method, assess the extent of the damage to avoid wasting money.
The paintless dent repair technique is truly ingenious. Through extensive experience, I've found that using flexible pry bars to push out dents from the inside of car doors is the most effective method, as it preserves the original paint throughout the process. The procedure involves first removing the door panel lining, then using strong lighting to locate the dent before applying gradual pressure to restore the surface. DIY attempts often fail due to difficulty in controlling the pressure or using rough tools. It's advisable to seek experienced professionals - costs typically range between 100-200 RMB depending on dent size, offering both speed and cost-effectiveness. For prevention, applying transparent protective film or choosing wider parking spaces can reduce collision risks. Most importantly, never attempt makeshift hammering as it may cause secondary damage leading to higher repair costs.
