Nasiol GlasShield Glass Coating — 2-Year Rain Repellent, 50ml
Nasiol GlasShield is a nano glass coating that makes windshields and mirrors repel rain for up to 2 years. Rated at a 106° water contact angle, water beads and blows off at speed — dramatically clearer wet-weather vision — while the film resists frost, UV and chemicals from pH 1–13. One 50ml bottle treats several windshields at just 5ml per m².

Does GlasShield work at highway speed?
Yes — that is where it shines: at speed, beaded rain slides off the glass, often with little wiper use, improving wet-night visibility.
How long does GlasShield last on a windshield?
Up to 2 years on glass in normal use — several times the life of typical consumer rain repellents.

Nasiol GlasShield — questions, answered
Does GlasShield really replace wipers in the rain?
At highway speed, mostly yes: with a 106° water contact angle, rain beads and blows off the glass, and many drivers use wipers only at low speed. It’s the single biggest wet-weather visibility upgrade per dollar in car care.
Is GlasShield safe for wipers and coated windshields?
Yes — it cures into the glass itself, rated to roughly two years of wiper use. Clean the glass thoroughly first; any oil film shortens its life. One 50ml bottle treats several windshields at 5ml per m².
GlasShield vs Rain-X style repellents — what’s the difference?
Consumer rain repellents are surface films that wash off in weeks. GlasShield is a nano coating that chemically bonds to glass: up to 2 years of repellency, anti-frost behavior in winter, and chemical resistance from pH 1–13. One application replaces a year of monthly re-treating.
Is this a genuine Nasiol product, and how fast will it ship?
Yes — Car Lab USA is an authorized Nasiol dealer, and every bottle of Nasiol GlasShield ships factory-fresh from our own warehouse in Mount Laurel, New Jersey.
