Any chance it has been in a shop or you have been welding/grinding close by? I've seen glass do that from hot sparks hitting the glass.
Sounds like micro-pitting. Can you feel anything with your fingernail? If there was any grinding done near the glass, the sparks will embed into the glass causing mirco-pitting and even the tiny chunk of burning metal (the spark) will get stuck in the glass. If it is pitted, the only solution will be replacing the glass.
it's most likely just pitted glass from tiny particles hitting your windshield on the highway. if you live some place that is dusty or in a big city with constant construction, it is going to happen. either replace it if it annoys you or wait for the yearly Jeep glass break and replace it then.
edit: you can use an orbital buffer and polishing compound to try and reduce some on the pitting.
Mine's had the same since I bought it. I just chalked it up to a LOT of small rock chips. Like the previous owner lived on a gravel road or something. I'd just try and ignore it if it passes inspection...
Do you just notice it when the sun is at a certain angle directly at the windshield? Then it is just the make up of the glass.
A near vertical pitted windshield. It's a Jeep thing.
Quick update, I could feel the chips on the glass through the finger nail. Driving around local I dropped into a glass guy and he advised a replacement for around 350$ .. He says he can polish for 80$ but advised against it.
Looked up Safelight quote and it says 240$ with national lifetime warranty on a non Jeep logo embedded and 390$ on a Logo embedded one. Planning to talk to the insurance today and see if that's covered.
Thanks for all your inputs on this folks.. For all deskjobbers like me .. butt cracks for the next 5 days.. Happy Monday :beer:
