Description
PIAA Silicone Wiper Refills ensure greater visibility by coating the windshield with silicone to promote continuous water beading in inclement weather. Water beads up into droplets at low speeds that are easily removed by ordinary wiping. And at higher speeds, wind pressure pushes the water off the windshield, often without even requiring wiper use. The silicone coating also reduces drag and eliminates annoying and inefficient chattering, regardless of the shape of the windshield to provide greater comfort for both driver and passenger. Silicone Wiper Refills reapply the silicone coating every time the wipers are used and fit Super Silicone, Aero Vogue and some OE wiper frames.
