Apply this, and rain will bead up and roll down the glass, cleanly taking with it any other water along the way. Just by driving at 45 km/h or more, all the water will fly off the glass! No surface preparation work required! Glaco Q coats the glass at the same time as removing traffic film or a previous coating. Shaped like a computer mouse, this easy to grip applicator cuts down on the time required to renew your hydrophobic glass coating.
