Is Car Coating or Crystal Coating Better?
3 Answers
Car coating is better, and its functions are: 1. Car coating has anti-oxidation and anti-aging effects. After application, it forms a hard inorganic coating layer on the car paint surface, closely combining with the paint to enhance the hardness and smoothness of the paint; 2. It can improve the glossiness of the clear coat on the car paint surface, making the paint look more vibrant; 3. The hard non-organic coating layer itself does not oxidize and also prevents external corrosion from acid rain, insects, bird droppings, etc., on the car paint; 4. The glass crystal itself has high-temperature resistance characteristics, effectively reflecting sunlight and external heat radiation to prevent high-temperature damage to the car paint.
As a veteran mechanic who's run an auto repair shop for twenty years, I've seen countless car owners struggle with the choice between ceramic coating and nano-coating. Ceramic coating is more affordable, costing a few hundred yuan per application, with effects lasting six months to a year. It provides decent water beading during regular washes, making it suitable for budget-conscious owners. Nano-coating is significantly more expensive, starting at over a thousand yuan, but offers higher hardness that can resist branch scratches and lasts up to two years—though it requires regular maintenance. If you frequently drive on highways or gravel roads, nano-coating provides better protection. Ultimately, it depends on your budget: choose ceramic coating for cost-effectiveness, or nano-coating for long-term protection.
As a regular at car detailing shops, I prioritize practical results. Coating mainly involves applying a layer of resin, which looks especially shiny under sunlight and has an impressive water beading effect when freshly done. Crystal coating uses silicon dioxide crystallization, feeling like glass to the touch, and genuinely protects against bird droppings corrosion and small stone chips. Last time my car got hit by a supermarket cart, the crystal coating prevented scratches, saving me repainting costs. Though it's pricier, its paint protection effect stands the test of time, proving more cost-effective in the long run.
