Why use Gtechniq G5 Water Repellent Coating for Glass and Perspex?. With non-factory applied glass coatings there is a direct trade off between longevity and repellency. Water will blow off car screens at speeds as low as 30mph and on vertical glass water will roll off and leave a virtually spotless surface.
