Winter Sucks & So Does Your Cold Weather Auto Glass Urethane


You've probably heard the old saying, "make hay while the sun shines", right?  Unfortunately, for Auto Glass Techs, we have to make hay while the sun hides, the snow comes down sideways, and jack frost nips at every exposed inch of skin.

Yes, cold weather auto glass installation ain't easy.  Consumers love the convenience of mobile auto glass installation and speedy service but rarely understand that plastic parts become brittle, moldings don't fit properly, and glass cleaner freezes. 

Many consumers are also ignorant to the fact that the safety of their Installation is dependent on the proper windshield adhesive.  Most consumers would be shocked to find out that many popular adhesives require 10 hours before they're safe.  Still more commonly used products are plastered with warning signs, "not recommended for use under 40F".

Yet the unsuspecting consumer is sent down the road in an unsafe vehicle with a warning to "keep your windows rolled down a crack and don't go to a car wash for 24 hours".  Sika_Titan_P2G_10_hour_SDAT-.jpg
