What are the pros and cons of automotive glass coating?
3 Answers
Automotive glass coating offers benefits such as corrosion resistance, easy cleaning, and high-temperature resistance; the drawbacks include color difference issues and maintenance concerns. Below is more information about automotive glass coating: 1. Introduction: Glass coating is a chemical polymer material. Due to its high-density chemical properties, it is widely used in the field of automotive detailing. Additionally, glass coating features high gloss, oxidation resistance, acid and alkali resistance, and UV protection. When applied to the paint surface, it enhances glossiness and isolates the paint from external elements, providing excellent protection. 2. Precautions: Glass coating should not be applied to rearview mirrors; anti-fog coating should not be applied too thickly; glass coating can still be applied even if the glass has been treated with explosion-proof film; avoid rain or car washing within 4 hours after glass coating application; anti-fog agents typically last for 1 month per application, while glass coating lasts for about 6 months per application; when selecting glass coating products, carefully check the product's formula and ingredients.
Having driven for over a decade, I tried coated glass and found the visibility exceptionally clear during rainy days—water droplets roll right off without frequent wiper use, and cleaning becomes much easier with tree sap and bird droppings washing away effortlessly. Additional benefits include UV protection, resistance to minor scratches, and extended glass lifespan. However, the downside is the cost—professional application runs several hundred to over a thousand yuan, with risks of bubbles or scratches if poorly done. DIY options are cheaper but often result in uneven application, significantly reducing effectiveness. Regular maintenance is also required, or the coating wears off in months. While beneficial, it's better suited for frequent highway drivers.
Coating has many benefits: excellent water repellency, rainwater slides right off, making driving much safer; it also prevents dirt and dust, reducing the hassle of frequent cleaning. However, I find the cost-performance ratio isn't great: professional installation costs thousands, which isn't cost-effective, and the coating degrades in about two years, requiring reapplication. DIY kits are available for just a few dozen dollars, but beginners might mess it up—applying too thick a coat can cause nighttime glare, adding risks instead. Considering these factors, I recommend budget-conscious car owners opt for affordable rain repellent sprays as an alternative—just as effective while saving money and hassle.
