I had my new windshield installed on Tuesday and today was the first day I could take it out for a drive. The windshield is PGW or Pittsburgh Glass Works, what used to be PPG glass. The installer did a great job, the fit is excellent and there is no distortion in the glass that I can see. I bought new exterior 2 piece trim for the windshield from a local Porsche dealer as I didn't want to use the installer's generic rubber seal. My glass insurance is going to cover that cost as well. Here's to hoping this windshield lasts for the next 15 years!
