The GM factory windshield installations is breaking the urethane bond between the urethane bead and the pinchweld fails. It failing because the factory isn't putting any pinchweld primer down or if they are using primer on the early 2000s models is primer on top of clear coat and not creating a complete bond because the clear is slick and primer won't adhere to the slick clear coat.
The removal tools y'all showed are out of date. We use up to date removal tools like a corded tool that uses a fiber cord to cut the urethane bead and does zero damage to the pinchweld. Also the primers have came a long way. The primer by Dow is both glass and pinchweld friendly. And can be used over the entire pinchweld surface or only on the area that got a nick or scratch when trimming the bead.
A ton of other factory windshield installation when the vehicle is manufactured is very sketchy whether it's a lack of adherence or the robot misses the preferred path for the urethane.

So glass urethane over OEM ecoat is ok? No epoxy needed in that situation?

Hi guys, what caused the fire? There are lots of rumors and misleading information out there.
