I think I will be giving Stoners a try. My other question is has anyone used the Diamondite spray clay or anything similiar on the windshield? I have not "deep cleaned" ever on the windshield and it just does not seem to clean up as nice as it used to. I can only imagine the amount of minerals that are left on it as it sits outside at the airport for 3 days and nights a week!
stoners invisible glass or megs nxt glass cleaner (their detailer line glass concentrate isn't bad either) are both great. IG is easier to find and available just about anywhere...
