What kind of glue is best when a windshield is installed?
A. There are many types of glue and caulking materials used and most are substandard. However, the glue or adhesive employed is a very important safety feature for your windshield. We recommend and only use Urethane. This adhesive must be strong enough to keep you inside the car in the event of an accident without a seatbelt. The urethanes used for windshields within recent years have a pressure rating of 500 PSI or more. A number of competitors still utilize butyl, which normally has a pressure rating of 50 PSI.
