07391 said:I had some bad water spots on my Jeep Rubicon's windows. Yesterday, I tried a glass polishing disk on speed 5 on my PC. First I used AutoGlym glass polish and it didn't work very well at removing the spots...then I tried Zaino Z12 glass polish, and it got off the water spots, but it left tiny microscratches that could be seen if examined in very bright sunshine. That sucks, so I won't be using that anymore. Good thing I just tested these products on my Jeep.
Then I came to a solution that will not scratch glass, and will get off the water spots. I used AIO on a foam pad on the PC at full speed. It takes longer, but the water spots are gone, and there are zero scratches. I also masked off the rubber trim around the windows so I could get all the way to the edges of the glass. Then I used isopropyl alchohol to wipe down all of the Rubicon's glass and remove the AIO, after which I applied Aquapel.
I had the same problem w/ the Zaino but it only occured on a older '97 Toyota Tacoma. I used it on a '05 Tacoma and a'04 BMW w/ out any problems. I'm guessing the older glass was a bit softer or something since it marred pretty easily.
