What Does Coating Mean?

[Colin]

Automobile coating refers to applying a special chemical agent onto the car's paint surface. This agent undergoes a chemical reaction on the paint surface, forming a thin, hard, and transparent protective film. This film protects the car paint from external dirt, impurities, etc., for a certain period, ultimately preventing oxidation, making it easier to clean, and maintaining the paint's shine. Car paint is frequently exposed to sunlight and complex air environments, forming a visible oxidation layer within 60 days. The formation of this oxidation layer leads to fading and surface roughness of the car paint. Although new cars generally have a protective layer, over time (usually around 3 months), the glossy oil on this layer thins and peels off, losing its protective effect. Therefore, within a few months of owning a new car, without paint protection, strong ultraviolet rays, acid rain, and dust can easily damage the paint. Thus, it is highly advisable to use coating as a protective measure for the car paint after purchasing a new car. Methods to Check Coating Products: 1. Look: Determine if it is a water-soluble series product. Genuine coating products consist of a series of three products, including "bonding agent," "base film," and "protective film," each clearly labeled. Additionally, when poured out, the product should be water-like, whereas fake coatings usually come as a single product, either paste-like or emulsion-like. 2. Smell: Check for any irritating odor. Pour a small amount of the product onto your palm and rub your hands together until they warm up. Genuine coating products have no odor, while fake ones emit a strong fragrance or other irritating smells. 3. Test: The ability to fully dissolve in water is a standard to identify if it is inorganic. Use a test tube or a glass of water for the test, adding a drop of the coating product. Genuine coating products will fully dissolve when shaken, as they are composed of inorganic substances like fluorine, silicon, cellulose, and glass. Fake coating products, however, will form a milky, cloudy liquid or clump, as they contain oily components that are insoluble in water.

Car coating is essentially giving your car's paint an invisible armor. This transparent protective layer isn't just a simple coating, but rather forms a stable crystalline layer on the paint surface using materials like silicon dioxide. The difference was especially noticeable on my old car - rainwater would bead up and roll right off, while dust and bird droppings couldn't stick. It's much more practical than waxing, as regular wax lasts at most two months, while coating can withstand UV oxidation for at least one to two years. The key benefit is that it also fills in minor scratches - after washing, when the sun hits the car, the whole vehicle shines like a mirror. However, it's important to find a reputable shop, as some use inferior materials that may turn yellow.

I've specifically studied the material principles of ceramic coating. Simply put, it involves using liquid glass to perform nano-level filling on the car paint surface, which forms glass crystals after high-temperature curing, with a thickness about one hundredth of a human hair. This structure has extremely strong hydrophobicity, with a water contact angle reaching 110 degrees. Experimental data shows that after coating, the paint hardness increases to about 6H, effectively preventing scratches from branches. I've tested different brands, and those with higher silicon content do last longer, but the application environment must be a dust-free workshop, with optimal crystallization effects when the temperature is below 30 degrees Celsius.

You know how people apply screen protectors to their phones? Car coating works similarly, but it's more professional. A specialized solution is used to form a transparent protective layer on the car's paint. When it rains, water droplets turn into little round balls and roll off, leaving no ugly water marks behind. Last time, I had my brother's new car coated, and washing it became effortless—just a couple of sprays with a high-pressure hose and it was clean. Bird droppings and tree sap are also easier to handle; a quick wipe with a wet cloth removes them without leaving stains. But a reminder: avoid getting the car wet for the first three days after coating to let the layer fully cure for better results.

Coating is essentially a chemical film-forming process. When liquid coating agents are applied to the car body, active ingredients penetrate into the paint pores, undergo oxidation and cross-linking, forming an inorganic silicon dioxide structural layer. This crystalline layer is exceptionally durable, resistant to salt, alkali, and high temperatures, making it particularly suitable for use in coastal areas of the south. After applying it to my five-year-old car's weathered paint, the previously hazy hood regained its factory-level gloss, and the swirl marks became much less noticeable. However, it's important to distinguish between coating and glaze sealing. Glaze sealing is a combination of filler and carnauba wax, which deteriorates after just six months of sun exposure. A genuine coating can be identified by a distinct rainbow halo visible in a dark room.

I remember back in the day when my mentor taught apprentices, he said: A good coating is judged by three criteria - lotus leaf effect, paint gloss enhancement, and durability. Genuine products make water instantly bead up and roll off, while fakes will spread into a thin film. During application, you must cure it three times with infrared lamps to achieve dense crystallization. Nowadays, some lazy shops use ceramic coatings to impersonate real coatings - those silicon-oil-based solutions look shiny at first but start turning sticky within three months. I've personally seen a luxury car whose protective film was removed after five years of coating, and the paint still looked brand new. This technology is truly impressive.
