Not yet on my 90.....that is it isn't noticable unless you look at the right angle for it. Tiny bubble-like formations can be seen in the right light and at the right angle....almost looks like streaks from a bad wiper blade. I can even see them from the inside of the car when I clean the glass, the Stoners makes them show up till you wipe it off.
Oh well, 22K miles and if it gets to where I can't see I'll do something about it. Until then I'll just drive & have fun!

Update
6 yrs down the road & another 22k miles added on to Her.
64k now and the bubble streaks have not worsened, still need moisture & the right angle to see them from inside the car. Can't be seen from a driving position & not visible from outside. The edges are starting to show a very little bit in the corners. Oh well, nothing lasts forever.
