It actually had ripples in places so vision was distorted as if you were looking through handmade glass. If you looked through the left side of the windshield the painted center line actually looked like it was wiggling..... and there was a place straight ahead where if you moved your head up or down the car in front changed shape. Not good.
I was worried I'd get a hard time from the service center, but the first thing the service manager said when he looked through it was "Man, that would make me sick...." So there was no hassle about getting it replaced, but I was also concerned about replacing something so integral to the build of the car. But two service centers told me the repair job would certainly be as good as new and maybe better, because they use a wider bead of sealant than the factory.
Picked it up this afternoon and all seems totally fine. Weird, though. I searched the forums and couldn't find anyone else who had that experience.
