Why does the original car paint peel off?
2 Answers
Peeling of the original car paint occurs when the primer is not completely removed; when the undercoat and primer materials are not polished multiple times, or when the paint quality is poor. Methods to prevent paint peeling: Park the car indoors as much as possible, preferably without a car cover. Regularly check the humidity inside the car. After washing the car, try to drive for a while. For soft paint surfaces, it's best to apply glaze sealing. Precautions for car painting: When performing car body repair and painting, choose an auto repair shop with a good reputation and skilled technicians. Car body repair is crucial; if not done properly, the car's surface will appear uneven, greatly affecting its appearance. Apply putty evenly. During painting, ensure a suitable environment—generally, a professional enclosed paint booth is standard to guarantee paint quality.
I've been thinking about the reasons for the original car paint peeling, and there are quite a few. Mainly, it's due to defects in the paint surface when it left the factory. For example, if the temperature wasn't controlled properly during painting, the paint layer is too thin, or it didn't dry thoroughly, prolonged exposure to wind and sun can easily cause it to crack. Additionally, long-term UV exposure makes the paint surface brittle, and combined with the temperature differences between cold winters and hot summers, the repeated expansion and contraction of the car paint can cause it to fail. Sometimes, owners using high-pressure water guns to wash their cars carelessly or parking under trees where bird droppings and tree sap can corrode the paint—these external factors can also accelerate peeling. The key is that good car paint needs a clear coat for protection. If the manufacturer cuts corners and the clear coat is too thin, problems are more likely to arise. I think regular waxing can extend the paint's lifespan, but once peeling starts, it's best to go to a professional shop for a repaint. Don't underestimate this issue—it not only affects aesthetics but can also lead to body rust, making repairs more troublesome later on.
