1 Answers
Sheet metal requires putty application because: The body panel after sheet metal repair is uneven and needs putty leveling before painting. The functions of automotive paint are: 1. Protect the vehicle from corrosion by various atmospheric agents; 2. Decorate the vehicle; 3. Identify vehicle types; 4. Improve comfort and sealing, preventing vibration-induced noise. Methods for automotive paint maintenance: 1. Regular car washing; 2. Waxing provides oxidation protection, static isolation, enhances paint surface brightness, and separates paint from dust and harmful gases; 3. Crystal coating applies a high-molecular film with hardness and smoothness to the vehicle surface, forming a protective layer; 4. Glaze treatment penetrates the paint to form a mesh protective film, enhancing paint strength.
