What are the methods for repairing small dents in car sheet metal?

Here are the methods for repairing small dents in cars: 1. Use a rubber eraser or a mixture of toothpaste and essential balm to remove the dent. 2. Pour boiling water over the dent or use a lighter with aluminum foil or a hairdryer to heat the area. Once softened, push the dent out from the inside with your fingers. A hot air blower can achieve the same effect. 3. Use a household plunger to handle the dent. Apply petroleum jelly around the edge of the plunger, place it over the dent, and pull hard to "suck" the dent out. 4. Visit a professional car dent repair shop for treatment.
When it comes to repairing small dents in car body panels, I've tried several methods myself that are quite effective and don't damage the paint. The most common approach uses the principle of thermal expansion and contraction - first heat the dent area with a hairdryer for 1-2 minutes to soften the metal, then immediately cool it down with ice cubes or cold water, which often makes the dent pop back partially. If the result isn't perfect, you can use a small suction cup tool - gently pull outward several times after attaching it to the center, being careful not to damage the paint. For dents near edges, avoid using excessive force. Also, try to park away from trees or tight spaces to minimize collision risks. After repair, applying some car wax helps conceal the marks, but for larger dents, it's better to let professionals handle them for peace of mind.
As someone who frequently tinkers with car repairs, I believe the key to fixing small dents lies in choosing the right tools. I've used the hot glue and pull rod method: first apply hot glue to the rod head and stick it to the center of the dent, wait for the glue to dry, then pull outward firmly to flatten it. Without tools, you can also pour some hot water over the dent and press it with a towel, but be careful not to burn yourself. After the repair, remember to check if the paint is intact—minor damage can be fixed with a touch-up pen. DIY repairs are cost-effective; a toolbox bought online costs just a few dozen dollars. However, don't get too ambitious and overdo it—if you damage it further, a repair shop could cost you hundreds, which wouldn't be worth it.
