Protective Glass Coating is an optically clear, low-maintenance coating that transforms ordinary glass or silica-based surfaces into a water-repellent surface. By filling in the microscopic peaks and valleys of the surface, it creates an ultra-thin, invisible barrier that protects surfaces from stains, corrosion, and other environmental pollutants. And just like a non-stick cooking pan makes cleaning easier and less frequent, so too will reduce cleaning time and the frequency of cleanings.
