A METHOD FOR INCREASING THE ABRASION-RESISTANCE OF A GLASS SURFACE COMPRISISNG TREATING SAID SURFACE WITH A MEMBER SELECTED FROM THE GROUP CONSISTING OF A ZIRCONIUM-CONTAINING COMPOUND AND A TITANIUM-CONTAINING COMPOUND WHICH ARE PYROLYZABLE TO FORM THEIR RESPECTIVE METAL OXIDES ON SAID GLASS SURFACE WHILE SAID SURFACE IS AT A TEMPERATURE AT LEAST AS HIGH AS THE PYROLYZING TEMPERATURE OF SAID COMPOUND, COOLING SAID TREATED SURFACE TO A TEMPERATURE BELOW 450*F. AND SPRAYING ONTO SAID STILL HEATED GLASS SURFACE AN OLEFIN POLYMER IN AN AMOUNT SUFFICIENT TO FORM A THIN, TIGHTLY ADHERING, TRANSPARENT, SUBSTANTIALLY COLORLESS COATING ON SAID SURFACE.
