What is the Function of Automotive Coating?

Automotive intermediate coating can firmly adhere to the primer surface and easily bond with the topcoat layer above it, serving as a connecting link between the preceding and the following. It has good moisture resistance and sanding properties, and can seal minor defects in the underlying layer, improving the fullness of the paint surface. The main functions of automotive intermediate coating include the following aspects: 1. Filling and leveling effect: The intermediate coating can fill tiny depressions on the substrate surface and sandpaper marks or pinholes left by sanding, serving a leveling function. 2. Isolation effect: The intermediate coating can further isolate the contact between the external environment and the vehicle body substrate, enhancing the rust-proof function of the primer.
The main function of automotive coatings is to protect the car body, ensuring my beloved vehicle suffers less wear and tear. The coating blocks ultraviolet rays from sunlight, preventing the car paint from premature aging and discoloration, especially during summer when UV radiation is intense—cars with good coatings still look new. Elements like rain, dust, and bird droppings can easily corrode the paint, but the coating provides a barrier, preventing contaminants from directly contacting the paint and reducing the risk of rust. My old car didn't have a coating, and after a few years, many small spots appeared on the surface, significantly affecting its lifespan. Additionally, coatings enhance the smoothness of the car's surface, making minor scratches less likely to form—for example, even if a branch scrapes the car while parking, it won't leave a mark. I recommend applying protective wax after regular car washes to complement the coating for better results. Although applying a coating costs some money each time, it saves a lot on repair expenses in the long run.
The coating keeps my car's color vibrant and shiny, making me happy every time I wash it—it looks as good as new. The coating covers the car's paint surface, forming a smooth layer that reflects light more evenly, making it shine brilliantly whether under the sunlight during the day or streetlights at night. The color doesn't fade due to wind or sun exposure; my red car still looks brighter than my neighbor's new one after three years. Stains like dust or raindrops are easy to clean, washing off with just a rinse, reducing the hassle of scrubbing. The coating also prevents rainwater oxidation, avoiding unsightly watermarks. When driving out for social occasions, the car's neat appearance boosts confidence and attracts friends who often ask about maintenance tips. I always recommend using high-quality coating spray—it's simple to apply and doesn’t require professional tools.
