Wow, you've been unlucky!
I've done a couple of glass windscreen installs and they fitted perfect.
No trimming, all holes lined up perfect, no shimming required, fitted the curvature of the airframe perfectly.
Both plastic screens off and glass on and sealed in 8 hours.
They have been on for more than 3 years with no issues and I've seen a 5 year old machine still with original glass windscreens with no issues or damage.
A bad batch perhaps?
I have only fitted them to AW machines, not Philly machines. Having accepted machines from both factories, I would have to say the Italians put out a better product. Hard to believe I know!
