PIAAs are 100% silicone and not just coated to the wiping edge and outperforms every other blade currently on the market: They are ideal for normal road use as well as off-road and competition driving in mud, fog, rain and snow, providing greater vision and more safety. After only a few minutes of use, the wipers coat the screen with a minute and invisible layer of silicone. This causes the rain to ‘bead’. Subsequently the droplets maintain a smaller surface area, resulting in a clearer screen and improved visibility. The silicone coating also ensures less friction between the wipers and screen surface, giving the blades a longer and more effective life. It also eliminates the probability of wiper squeak.
