What is the reason for spraying coating agent on the windshield?

It can cause the glass to become rough and increase the friction coefficient, but the coating can be washed off, causing little damage to the glass. The relevant introduction about coating is as follows: Coating Introduction: Car coating is a paint protection project that applies non-petroleum environmentally friendly materials such as glass cellulose, silicon polymer, fluorine polymer, and high-purity water to evenly coat the paint surface with a hard, oxidation-resistant inorganic film. Through a chemical reaction with the paint, it forms a glass protective layer to shield the paint from external damage, enhance paint hardness and brightness, and make the car body smoother and more lustrous. Coating Function: Car coating agents differ from car wax in that their molecules are smaller, forming a tighter and more durable protective layer on the car's paint surface. This layer can repel water, resist acid rain, block UV rays, and prevent paint oxidation and fading.
I use a coating spray on the windshield mainly because it forms a protective layer that is very practical for waterproofing and dustproofing. During daily driving, rainwater or mud splashes can easily stick to the windshield, obstructing the view, which is quite dangerous. After coating, the surface becomes smooth, and rainwater slides off with just a rinse, reducing the need for wipers and minimizing wear. It also protects against UV rays, preventing the glass from aging due to sun exposure and extending its lifespan. Some premium products contain hydrophobic agents, causing water droplets to roll off quickly, providing an exceptionally clear view. Additionally, the anti-static function reduces dust adhesion, making it easy to clean the glass with just a wipe. The cost is also low—applying it once can last for several months, making it a handy car maintenance trick. Overall, the main reasons are to enhance driving safety and convenience.
I regularly apply a coating agent to my windshield to simplify maintenance. During rain or snow, using the wipers can easily leave scratches or stains on the glass, affecting visibility. After application, a protective film forms, allowing rainwater, bird droppings, or dust to be wiped off effortlessly, saving time and effort. It also prevents freezing, reducing frost and ice buildup in winter, avoiding the hassle of cleaning the glass before driving. Long-term use minimizes glass corrosion and damage, saving on replacement costs. Additionally, the coating agent blocks UV rays, indirectly protecting the interior from fading. I apply it quarterly—it's affordable yet highly effective, maintaining the vehicle's clean appearance. Simply put, it's a smart choice for routine maintenance.
