Not on my G35 Coupe [img]/w3timages/icons/smile.gif[/img], they're all over my wife's company van. The sprinklers around her car spray her van sometimes (long story). We have hard water. Products that we've tried:
MX-7 (for paint), helped but only about 50%

Numerous window paste/thick liquid cleaners: Extremely hard to buff out, takes a lot of buffing. Gets the job done, if you don't want your hands attached to your arms any more. [img]/w3timages/icons/smile.gif[/img]

100% pure vinegar. Helps, even used with a razor blade. Spots still there.

Locally in Hawaii, they make a product called MX-7 that takes off water spots for paint so easy. I want to find something that's just as easy. Each time I see a new water spot removal product, I buy it hoping it will work good.

I'm tempted to try a product called CLR (Calcium/Lime/Rust) to see if will work. Anyone else have any suggestions?

I just want my wife to be able to see out of her windows for safety reasons.

If you use something like CLR or LimeAway, make sure you put on rubber gloves, and try to keep it off the paint -- not sure what it would do to a paint finish, but it will eat your hands. I'd test it in a small corner, too, to make sure it doesn't eat the glass.

You may need to get that professionally detailed. Detail shops carry the proper tools and chemicals to help remove most oxidation, scratches, chemical etching, water spots, etc.

 

A product i used to use on my PWC named "Ducky" works pretty good. Should be able to find it or something similar at your local boating supply store.

 

zaino sells a glass polish that works quite well to remove all contaminants from glass.

id recommend using that before using clr. if you want send me money for shipping and ill ship my bottle out to you and you can ship it back when your done. =P

 

i've never tried it on glass but wouldn't a claybar work as well since it works wonders on the paint.
