How to Fix a Dented Car Trunk by Yourself?

To restore the dented area on the car body to its original shape, it must be completed by hammering and welding, etc. Before painting, to ensure the body color is consistent. Uneven areas after sheet metal work need to be smoothed with a type of clay (commonly known as putty). Paint is then sprayed onto the damaged surface. Different grades of sandpaper are used to smooth out the uneven surfaces of the putty. To quickly dry the paint, the vehicle needs to enter a paint baking room for 'drying' operation. To prevent rust, a layer of anti-rust paint needs to be sprayed. Reinstall the parts that were removed before the sheet metal work.
I remember last time my car was parked in the neighborhood, and a neighbor bumped into the trunk leaving a small dent. I fixed it myself using a heat gun and a suction cup. First, I bought a car-specific suction cup tool online for just a few dozen yuan. The trunk surface needs to be thoroughly cleaned, then use the heat gun to blow on the dent for a few minutes to soften the metal. Next, firmly attach the suction cup and slowly pull it out with even force. If you don't have the tool, try hot glue: apply the glue, wait for it to dry and harden, then pull directly. Be careful not to burn your hands during the process—wearing gloves is safer. After the repair, there might be slight marks on the paint, but overall it's quite smooth, saving the cost of going to a repair shop. When driving or reversing, always be more observant to avoid similar minor accidents.
As someone who often tinkers with cars in the backyard, I handle trunk dents with great care. Prepare a suction cup and a heat gun, and make sure the dented area is thoroughly cleaned and free of dust. When heating, keep the temperature moderate, using medium heat for about three to five minutes. Gently push or pull the suction cup with steady movements—avoid jerking it suddenly to prevent damaging the inner structure. These tools are readily available online, affordable and practical. Ensure the workspace is well-ventilated and avoid working when kids are running around. If the dent is deep or the edges are cracked, it's best to stop and seek professional repair—don't risk compromising the car's structural safety over a minor issue.
