Mita silicone wiper blade applies an invisible water-repellent film coating onto the windshield after moving the wiper blade across the clean dry windshield for just 3 minute. This kind of coating fills the penetration of water molecules, which promotes continuous water beading and makes droplets bounce off the glass in inclement weather. When at a speed of 80Km/h, the raindrops rolling backwards and flying up, which maintains a clear view even without turning on the wiper. It greatly reduces the frequency of rain wiping and ensures the safety of driving in rainy days.
