How to Fix Dents on Car Body?
2 Answers
The methods to fix dents on car body are: 1. Use small suction cups to repair minor dents on car doors. Attach the suction cup to the dented area. If the dent is large, prepare multiple suction cups and evenly place them at the center of the dent, then pull outward forcefully with tools; 2. Use hot water to repair car body dents. Dent repair is based on optical, physical, and mechanical principles, using leverage to address dents of various sizes and depths caused by external factors. This method is applicable when the car's paint surface is not damaged and the metal surface has not been excessively stretched, representing a modern repair technique.
I've dealt with dents in car bodies several times. Small dents can be completely fixed by yourself - just use a strong suction cup to pull from the center of the dent outward, applying steady force slowly. If you don't have a suction cup, pour hot water on the dent and immediately use compressed air to blow or dry ice to cool it, utilizing thermal expansion and contraction to pop it back. This works well but only for plastic or unpainted metal parts. Last time I had a small dent on my car door and restored it using this method, saving over 200 bucks in repair costs. However, be careful as applying too much force might scratch the paint or cause deformation, so I only recommend this for minor dents smaller than a coin. After repair, apply some car wax for protection. DIY repairs are both fun and cost-effective, a practical skill to have, but for larger dents it's better to visit a professional shop to avoid complications.
