Why Does a Car's Paint Naturally Peel Off?
1 Answers
There are many reasons for paint peeling, mainly falling into three categories: 1. Impact: Paint peeling caused by scratches or collisions; 2. Spraying Quality: Paint peeling due to issues during the spraying process, such as low-temperature painting, expired paint, excessive dust on the car body surface, overly thick paint film, poor primer quality, or problems with putty quality, among others; 3. Body Panel Quality: Issues with the quality of the body panels themselves. For example, high levels of sulfur, phosphorus, or other impurities in the body's sheet metal can lead to electrochemical corrosion, causing rust in the internal sheet metal of many new cars within about 3 years. There are numerous causes of paint peeling, including excessive car washing and prolonged exposure to UV rays, which are also significant factors.
