Different materials of cars require different repair methods. Below are the specific introductions: 1. Plastic Body Dents: For small and slight dents, you can use a lighter behind aluminum foil or a hairdryer to heat the area until it softens, then push it out from the inside with your fingers. Alternatively, pouring hot water directly on the dent can achieve the same effect. 2. Aluminum or Metal Body Dents: You can apply petroleum jelly to the edge of a plunger, place it over the dent, and pull it out with force. This method is only suitable for relatively regular and not too sharp dents. For sharper dents, it is necessary to go to a specialized car dent repair shop for treatment. Below is more information about car dent repair technology: 1. Meaning of Dent Repair Technology: Car dent repair technology is also known as sheet metal work or non-marking and non-destructive technology. 2. Principle of Dent Repair: Car dent repair technology restores the body's dents without damaging the original car paint. The principle is based on optics and mechanics, using the lever principle to gradually restore dents of different depths to their original factory condition (similar to a phone's factory reset).

I often encounter small dents on car doors. First, feel the depth of the dent with your fingers. If it's just a shallow surface dent, you can try a DIY method: pour boiling water over it for thermal expansion, then use a large toilet plunger to firmly suction the center—it often pops back out. After drying, apply some touch-up paint to prevent rust. If the dent is deep or severely deformed, don't mess around—take it to a professional repair shop for metalworking. Spending a few hundred bucks is better than letting rust ruin the entire door. When parking, avoid tight spaces to reduce collision risks, and adding edge guards to door corners works well too. After my last repair, I drove with much more peace of mind—fixing small issues early saves big money later.

My car door also got a small dent, which didn't damage the paint but was a bit unsightly. After checking online guides, I bought a car dent puller tool for just a few dozen yuan on Pinduoduo. It's simple to use: first soften the plastic area with a heat gun, then attach the suction cup and slowly pull it out. Remember to clean the surface to avoid leaving debris. If DIY isn't your thing, local quick repair shops usually charge around a hundred yuan. For insurance claims, minor damages like this typically aren't covered unless it's a major accident. Regularly inspect your car's edges when driving, choose open parking spots by the roadside, and develop good habits to prevent future damage—saving hassle and extending your car's lifespan.

Small dents on the car door were fixed by my husband at home using a hairdryer to heat the area, then using a powerful vacuum cleaner nozzle to pull the dent back into shape—simple and cost-effective. After fixing, apply a layer of car wax to isolate the area from air and prevent rust. For larger dents, it's better to spend a little money at a repair shop to get them fixed rather than waiting for the damage to worsen and needing to replace the entire door. Regular car washing and maintenance, along with paying attention to the condition of the door panels, are essential.
