Do OEM Car Doors Need Painting?

[KayleeRose]

OEM car doors need painting. Newly replaced doors come without color, only coated with a layer of primer. The color paint for the car still needs to be purchased and applied separately. Functions of Automotive Paint: Automotive paint generally refers to the coating applied to the car's surface. This coating involves applying a thin film over the car's paint to protect the gloss from fading and to provide a physical protective layer, thereby safeguarding the paint. Principles of Automotive Paint: The main component of car paint is resin, which has relatively large molecular gaps. After coating, small molecular elements such as silicon, silicon dioxide, and nano-inorganic silicon in the coating solution can fully penetrate into the gaps and micropores of the paint molecules, forming a transparent crystalline layer similar to a smartphone screen protector on the surface. This significantly enhances the hardness and scratch resistance of the paint surface, providing long-term sealing protection and keeping the paint looking bright and new for a long time.
