here is what i have done.
i have read the tips and tricks section, multiple times.
i have tried regular wash, windex, vinegar, 0000 steel wool, waxing (which helped a little on the previous car), and rain-x, and NOTHING has taken off the water spots. the only thing i haven't tried that i have read about is Invisible Glass. i don't want to go out and buy it if it is going to work like everything else i have tried. anybody have any more ideas? any help is appreciated.

I take it this is on your windows? Don't bother with Invisible Glass, it's not a miracle product, just another glass cleaner.

What you need is a glass polish as sold by Autoglym, Zaino, Duragloss, and I'm not sure who else. Those are the bigger names for that though. Use it like a polish on your paint and rub it in. It may take some working, but that should do it.
