Which is Better for Cars: Crystal Coating or Film Coating?
2 Answers
Automotive crystal coating is better. Here are detailed introductions about it: Introduction One: The hardness of diamond crystal reaches 6H, compared to the 2H hardness of ordinary car paint, it can prevent most minor scratches and has its own elastic recovery function. Introduction Two: The ultra-fine nano-crystal layer of diamond crystal isolates the paint surface from the external environment, effectively preventing oxidation and resisting corrosion from bird droppings, insect fluids, acid rain, etc. Introduction Three: Diamond crystal is resistant to UV rays, high temperatures, and extreme cold, with a temperature resistance range of -50℃ to 300℃, adapting to a wide range of temperature changes without cracking or peeling.
I've been driving for over a decade and have tried both. Ceramic coating is more suitable for owners seeking long-term protection. The crystalline layer it forms has high hardness, resisting scratches and UV rays, with effects typically lasting 1-2 years, priced between 2,000-4,000 RMB. Paint sealant is more basic, being a liquid polymer coating mainly for gloss enhancement and hydrophobicity, lasting about half a year, priced at 800-1,500 RMB. I recommend ceramic coating for frequent highway drivers or older vehicles, while new car owners or those on a budget can try sealant first. Remember, thorough paint polishing is essential before application, otherwise any coating is useless. For daily maintenance, just use pH-neutral car shampoo, but hard object scratches will still cause damage.
