Unlike regular rain repellent coatings that adhere to the glass surface with relatively weak physical bonds, G1 uses a chemical bond that gives G1 unparalleled durability.
G1 ClearVision Smart Glass is extremely durable, its hydrophobic feature improves visibility in wet weather, which improves safety and eye fatigue. It also makes it much easier to remove contaminants from the glass, such as ice, insects and tree sap.
G1 only works on glass substrates and thus does not work on modern headlight lenses made of polycarbonate. For this, you must use G5 Water Repellent for Glass and Perspex.
Choose the 15 ml bottle only for windshields, but the 100 ml bottle if you want to use on all the glass of your car. Gtechniq G1 ClearVision Smart Glass comes with G2 Residue Remover.
