Nasiol GlasShield is a powerful nano rain repellent designed specifically for car windshields and exterior glass. Its ultra-high water-repellent formula promotes safer driving and clearer visibility with less reliance on windshield wipers, which is especially valuable in rain and snow. Once applied, it bonds to the glass and turns water into tiny beads that roll away, so the wipers see far less use. GlasShield works on all types of auto glass and offers up to 2 years of durability, 30,000 miles of driving, or about 80,000 wiper-blade cycles. Kit contents will treat all exterior glass on most vehicles.
