What are the effects of bodywork and repainting on a car in the long term?

Introduction to the effects of bodywork and repainting on a car in the long term: 1. Impact on the car's resale value: When the car has significant dents, the bodywork may deform. During repairs, methods such as cutting, stretching, or sanding are used to correct the bodywork, followed by applying putty to shape the body, and finally repainting. Any repainting of the car will result in a discount during later sales, and the larger the repainted area, the lower the price. 2. Reduction in body strength, thickness, durability, and pressure resistance: After bodywork cutting, putty is used to fill the dented areas. The filled body will have lower strength, durability, and pressure resistance compared to the original aluminum body. Additionally, processes like bodywork cutting can thin the original body panels, making the repaired areas more prone to deformation later. For better results, specialized aluminum powder and curing powder can be used to fill dents, but this comes at a higher cost. 3. Reduced durability of the paint and color mismatch: Repainting must consider the heat resistance of components, so the temperature is limited to 50-80°C. If the repair technician's skills are inadequate, issues like paint mist, runs, color mismatch, discoloration, and orange peel may occur later.
