What are the effects of repainting a new car?

The effects of repainting a new car: 1. It can damage the phosphating layer and electrolyte layer: These two layers play a crucial role in preventing corrosion of the metal substrate. Once damaged, ordinary repair processes cannot restore them, so many cars that have undergone sheet metal and repainting are prone to rust. 2. Affects aesthetics: After sheet metal repair, the metal surface becomes uneven, and fillers like putty are typically used to level the surface. However, the expansion coefficient of putty differs from that of metal, leading to cracking and denting over time, which affects the appearance. 3. Changes in paint strength and hardness: In the painting workshop of an automobile factory, the paint is baked at around 200 degrees Celsius, making it very hard and strong. Repair shops, however, can only achieve 70-80 degrees Celsius, resulting in paint that is less hard and strong than the original factory paint. 4. Color difference over time: No matter how skilled the later repainting is, color differences will inevitably appear over time, and the repainted surface will age faster than the original factory paint. This is because the repair paint is not as high-quality as the original factory paint, and the spraying process and environment are significantly different. 5. Reduced resale value: Large-scale repainting can affect the vehicle's resale value. For example, under the same condition, a repainted car will be cheaper than one with minor scratches that hasn't been repainted.
