Is Car Rain Repellent Useful?
2 Answers
Car rain repellent is useful. The main component of rain repellent is a nano-organic active agent. After spraying, it forms a nano protective film on the glass surface. The water repellency is mainly achieved through physical characteristics, without any chemical reaction, corrosiveness, or pungent odor. The method of using car rain repellent is as follows: 1. Clean the windshield with a towel; 2. Shake the rain repellent gently and spray it evenly on the car glass; 3. Use a clean, dry sponge to evenly spread the rain repellent sprayed on the car glass; 4. After the glass surface dries, use an all-cotton dry cloth or tissue to wipe the glass surface until it becomes shiny.
I've been driving for over a decade and tried all kinds of automotive rain repellents. To be honest, it really works! After spraying it on the windshield, rainwater doesn't flow down stickily as before but instead forms tiny beads that quickly roll away, instantly clearing the view. Even when driving on highways during rain, I don't get blinded by water splashes anymore, significantly reducing accident risks. The one I use is a domestic brand costing 30 yuan per bottle, and one application lasts several weeks—much more cost-effective than constantly replacing wiper blades. Now I apply some every time I wash my car, and maintenance is simple with no need for professional tools. The key is its chemical coating that prevents glass aging, making vehicle upkeep much easier.
