The Invisible Windscreen Repair Menace

One problem that plagues windscreen repair technicians is the use of various hydrophobic coatings. The coatings cause water to bead up and roll off windshields. The problem they pose for repair technicians is that these coatings prevent repair resins from fully bonding to the glass which may cause the cured pit resin to pop out when scraping a repair flush.

Rain-X® and Aquapel® are probably the most common coating products. It is always a good idea to test the windscreen. See if there is a coating application before starting the repair. To achieve this, cover the area to be repaired with a Chip Saver patch to prevent liquid from infiltrating the break and spray it with water or glass cleaner.
