It is recommended to take your car to a professional auto repair shop for minor surface dents to avoid causing secondary damage. While dents may appear easy to repair, there are significant limitations. If the paint is damaged, the dent cannot be repaired. Additionally, dents located near wheel arches, edges, or A/B pillars are also difficult to fix. Small dents on the car body can be addressed using traditional metalworking repair methods or a dent repair tool: Metalworking Repair: Generally, although metalworking repair is more expensive and requires highly skilled technicians, it yields the best results. Metalworking repair involves restoring the deformed parts of the car's metal shell. For example, if the car body has a dent, metalworking can restore it to its original shape, followed by applying specialized paint to make the repaired metal surface as smooth and shiny as the undamaged areas. Dent Repair Tool: This method uses tools like a hot glue gun and a bridge-style suction puller. The suction cup adheres to the car body, and the dent is pulled out using tension. The operation is simple and can be done by yourself. Additionally, some car models have softer body materials. When heated with hot water on small dented areas, the material softens, allowing the dent to be pulled out directly with a suction tool. However, this method does not work on iron or aluminum car materials, and professional repair services should be sought in such cases.

Last month, I got a small dent from a shopping cart while parking and fixed it myself with a suction cup tool. Just a few simple steps: first, clean the dent area to keep it dirt-free, apply some soapy water to enhance suction, then press the suction cup firmly and pull slowly until you hear a pop sound indicating it's back in place. If the dent is too deep or has creases at the edges, don’t force it to avoid damaging the paint, which would be more costly than worthwhile. I recommend beginners watch tutorial videos first and buy a DIY kit online for a few dozen bucks to practice. To prevent dents, park in spacious spots and avoid windy days when objects might fly and hit the car. After several DIY attempts, I find small dents manageable, but for major issues, it’s better to seek professional repair to save time and hassle.

Having driven for over a decade, I've seen many small dents. Experience tells me to handle them case by case: for shallow dents with smooth edges, pouring hot water followed by rapid cooling (like pressing with ice) can make the metal expand and contract, possibly popping the dent back out. Areas near doors or side mirrors are prone to deformation—it's best not to tamper with them and instead take them to a professional body shop for safe and reliable repair. I once tried fixing a dent myself and ended up scratching the paint, costing me extra for touch-ups. For prevention, regular car washes and paying attention to the body, avoiding obstacles in parking spots, are key. Professional repair shops have skilled technicians, charging about 100 to 300 RMB per dent, with high efficiency and no damage to the car.

As a budget-conscious car owner, DIY is the first choice for minor dents: buy suction cups or hot glue repair kits online for 20 to 50 yuan, with a simple peel-and-stick operation that takes just minutes. If unsuccessful, then seek a professional shop, costing over 100 yuan per repair. Weighing cost-effectiveness, DIY is sufficient for minor flaws; but for larger dents or sensitive locations, go straight to a repair shop to avoid additional damage and higher costs. Driving carefully and parking away from risk sources can save trouble—spending small money to handle big issues is the most practical approach.
