I've never had an issue with a seal on replaced glass. Go for it and enjoy
Yea, they can suck that way. Years ago I had a plastic guard under one of my cars that had to be dropped every oil change, by the time I sold it, there was maybe 3 screws left to hold it upI never had a seal issue on a windshield replacement, but the installer did break the clips holding the trim pieces on each side of the windshield and failed to replace them. I ended repairing those myself.
