I had my windshield Diamond treated at the dealer (baked it I think), and I have not had any issues whatsoever. They warranty it also for 4 years no questions... Just a thought for people who are replacing theirs a lot. About $400 extra, but worth it. 33k miles, and 1 year old. 40/60 off/on road miles.
Also, I live in an area with VERY high winds and a long commute to work with hard winters. No problems. They even fix stars and cracks for free.
