What are the consequences of 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 related introduction of coating is as follows: Coating Introduction: Automobile coating is a paint protection project that applies non-petroleum environmentally friendly materials such as glass cellulose, silicon polymers, fluorine polymers, 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 that shields the paint from external damage, enhances paint hardness and brightness, and makes the car body smoother and more lustrous. Coating Function: Automobile coating agents differ from car wax in that their molecules are smaller, allowing them to form 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 remember once when I was washing my car, I accidentally sprayed the coating agent onto the windshield. Originally intended to enhance the body's protection, it turned into a big trouble. Once on the road, when it rained, the water droplets wouldn't flow at all, leaving a sticky, blurry mess; the wipers made harsh noises and couldn't clean the water stains properly. At night, it was even scarier—the headlights reflected intensely, scattering my vision, and I nearly rear-ended a car several times. After getting home, I tried ordinary soapy water to no avail. Consulting a car repair technician, I learned that a glass degreaser was necessary to repeatedly scrub, taking a full half hour to remove the residue. A reminder to everyone: it's crucial to apply products in designated areas when washing the car. Coating agents are only suitable for painted surfaces; once they come into contact with glass, they form an oily film layer, affecting the lifespan of the wipers and potentially scratching the surface. Small daily mistakes can lead to major hazards—safe driving relies on clear visibility.
