What is the purpose of automotive coating?

Here are the functions of automotive coating: 1. Anti-oxidation and anti-aging: After application, a hard inorganic (silicon dioxide glass crystal) coating layer is formed on the car paint surface, tightly bonding with the paint to enhance paint hardness and smoothness, completely isolating the paint from air, and never falling off without external force. 2. Glossiness: It can significantly improve the glossiness of the clear coat on the car paint surface, making the paint appear more vibrant and dazzling. 3. Corrosion resistance: The hard non-organic (glass crystal) coating layer itself does not oxidize while also preventing external corrosion from acid rain, insects, bird droppings, etc. The dense glass crystal coating has super corrosion resistance, effectively preventing damage from corrosive substances like acid rain and preventing paint discoloration. 4. High-temperature resistance: The glass crystal itself has high-temperature resistance characteristics, effectively reflecting sunlight and external heat radiation to prevent high-temperature damage to the paint. 5. Scratch resistance: The hard non-organic (glass crystal) coating layer can increase the surface hardness of the car body to 7H, far exceeding the 2H-4H hardness of car wax or glaze, providing better protection against damage from sand and gravel.
I found that ceramic coating mainly adds a protective shield to the car paint, making it harder for UV rays, rainwater, or bird droppings to stick, directly protecting the original paint from scratches or discoloration. This keeps the car looking shiny and new, and washing becomes super convenient—just rinse with water a few times and it's clean, saving me from queuing at the car wash. In the long run, ceramic coating is much more durable than waxing, lasting about a year with one application. It costs a bit but saves time and money on waxing. Additionally, it provides corrosion resistance, protecting against acidic rainwater or road debris, preventing damage to the paint and avoiding expensive repairs. I recommend choosing high-quality ceramic coating products and maintaining them regularly with mild cleaners to ensure long-lasting results.
The coating is amazing. After application, the car body becomes super smooth, water droplets roll right off without leaving marks, and you don't have to worry about the car getting dirty after driving in rain or on muddy roads. Just rinse it with a hose when washing—no need for strenuous scrubbing. It also makes the paint shine brilliantly, turning heads when parked outside. I've tried it myself—stains wipe off easily, even bird droppings aren't a problem. Although the initial cost is higher, it saves money compared to frequent waxing and reduces environmental impact. I now make it a habit to get it done annually. Friends recommend professional shops for better results, and daily maintenance is a breeze.
