Help me with my windshield!

There are 2 different methods. I wont debate which is best or easiest.
To put the gasket on the glass first, then pull that assembly in with a rope is probably the most common method for all vehicles of this era/design. I'll assume that's the easiest, whether best or not.
I've seen auto glass get a milky look around the edges or what looked like air bubbles between layers. I was told the cause of that was the raw edge of the glass sitting in water. I don't know if that's true or not. Just incase... I apply the butyl sealant between car and gasket and between glass and gasket. To do that I have to put the gasket on the car first.
I've done only 5 windshields and 3 notchback rear glasses ( one of those wasn't my car ). Always had a big mess to clean up but none of them leaked. And just for the record... Every one was with a used OEM gasket.
Good luck whichever way you go.
