My friend works at a auto glass shop. He got me a job there not to long ago. I've been working there for about two weeks now and have learned a lot about auto glass.:read2:
It's a special type primer that goes around the pinch welds before the urethane is applied. It takes about 6 minutes to dry. Then there is a special type etching primer that goes on the perimeter on the inside of the glass. It is clear or black. In your case (older cars) it will be black. That takes 6 minutes or so to dry. Other than that it is installed like he installed it. It can be done various ways but the boss insists we do it this way. It suppose to be full proof without leaks. It's more of a modern way of doing it. We did a Chevy II Nova last week.
