Maintaining clear visibility in rainy weather is important in reducing drivers' work load. Water repellent glass is a useful technology for this purpose, because it provides better visibility by forming water droplets instead of a water film. However, water repellents have certain drawbacks, including a shorter service life than desired. There are strong demands for water repellent glass with a longer life. This paper presents a new type of water repellent glass system consisting of an inorganic base layer, with a larger surface area, and a water repellent layer with a fluorine functional agent. Besides providing a much longer life, the new glass system is hard enough to be used for the side windows of hardtop vehicles
