Our car windshield de-wetting agent (30ml) contains polymers and absorbents. It can form a hydrophilic transparent film on the glass surface, pre-draining the water droplets on the surface, and has a long-lasting and waterproof function. The usage method is very simple: clean the surface and wait for it to dry. Keep the surface dry. Shake well, then spray a small amount of liquid onto the surface and gently apply the coating with it. After 3-5 minutes, wipe the coating with a dry towel until the surface is clean. Moreover, it can increase the water surface of the glass, be waterproof and not prone to accumulate raindrops.
