What are the disadvantages of crystal coating?

[Grover]

High cost, extremely demanding requirements for construction environment and technical skills are all disadvantages of crystal coating. Below is a detailed introduction to the drawbacks of crystal coating: High cost: The comprehensive market price of crystal coating ranges from around 1000-5000. For automotive maintenance and beauty treatments, crystal coating is quite expensive. Extremely demanding requirements for construction environment and technical skills: Crystal coating application is complex and requires strict conditions. It must be performed by professionally trained crystal coating technicians in a dust-free environment. The skill level of the technician directly affects the effectiveness and lifespan of the coating. Crystal coating application can wear down the car paint: Before applying crystal coating, the car paint needs to be polished. Generally, a car can withstand about 7 polishing sessions. The lifespan of one crystal coating application is around 2 years. Too many applications can have the opposite effect, damaging the car paint.

Having driven for decades, I find the biggest headache with ceramic coating is the high cost. A single application usually costs several thousand yuan, but the effects don’t last long—at most two or three years before needing a redo. Last time I got it coated, the paint’s shine noticeably faded within just a year, and water beads during rain easily attract dust, making cleaning a hassle. Plus, the maintenance is expensive—you can’t use regular car wash soap and must buy specialized products, or else the coating gets damaged. In the long run, this expense is better saved for maintenance or repainting, as the cost-performance ratio is much lower, especially for budget-conscious car owners. It’s simply not worth the price, and I’d rather save the money for new tires.

Last year, on a whim, I got my new car coated with crystal wax, thinking it would make the car look shinier. But maintaining it turned out to be a real hassle. The coating is very thin, and even minor scratches or slightly aggressive washing can cause marks. The car's surface also attracts oil stains and bird droppings easily, leaving traces if not cleaned promptly. Moreover, using regular car wash detergents or brushes can damage the coating, forcing me to spend extra time and money on specialized cleaning products. Over time, the protective effect diminishes, with rain washing revealing unsightly spots, and the overall gloss doesn’t last long—it felt like a waste of money. In hindsight, simply waxing or applying a paint protection film might have been more practical, saving both money and effort.

I believe the biggest issues with ceramic coating are environmental impact and health risks. The application process often releases strong chemical odors. Like when I had it done before, the pungent smell lingered for a long time before dissipating, likely due to solvents or resin materials used - improper handling could harm the environment. Additionally, the products contain chemicals that may irritate skin with prolonged exposure, especially for sensitive individuals. The performance is also subpar, leaving water marks after rain and requiring maintenance with eco-friendly products that add burden. Traditional wax or biodegradable coatings would be better choices - more economical while being greener and safer.

From a professional perspective, the application flaws of crystal coating are crucial. It demands skilled techniques - uneven application or poor temperature/humidity control can lead to bubbling or peeling. I've handled numerous cases where car owners complained about fine cracks or flaking occurring within months, caused by incomplete dust removal or improper base layer preparation. Maintenance is also problematic - the thin coating has poor scratch resistance and can be damaged by flying gravel. Worse still, repairs are costly as entire sections need redoing, and standard car washes often lack the proper techniques, potentially making it worse. If you insist on getting it done, I recommend finding an experienced shop, though costs will skyrocket.

I'm not satisfied with the daily experience after getting my car ceramic coated. The protective layer is too thin - small road pebbles easily leave scratches, and the anti-scratch performance falls short of advertised claims. Water marks are extremely noticeable after rain, requiring additional water spot remover after every wash. Compared to PPF, ceramic coating has weaker durability - the gloss fades significantly within a year and a half, and rain stains become harder to clean. The price isn't cheap either, starting from over 2,000 RMB per application. In practical use, regular waxing or simple polishing proves more cost-effective and hassle-free, especially for daily commuters - this treatment really isn't worth the trouble.
