The Unrivaled, state-of–the-art water repellent product. Added strength protects against glare, water and road debris. A windshield treated with StayNu Dynamic Glass greatly increases a driver's vision by shedding water. The phrase is hydrophobic, meaning that the treated glass surface reacts with water to not permit it to rest upon the glass. Nanotechnology concerns the process of building products at a smaller molecular level to enhance the strength of the item. Dynamic Glass has been engineered to act at a molecular level to increase its strength. Dynamic Glass provides a barrier to resist cracks.
