Hi Guy!
Wax won't remove water stains. I've used 3M Rubbing Compound (clear coat version) to remove water stains from my Dad's black truck. It also removed scratches from my Stepmom's new car. I was impressed by the results. The only caution is, do NOT use a buffer as the rubbing compound heats up quickly. When you use it by hand, it is very gentle, and will make the finish on your Aries POP!
So, when we have lunch, I want to hear about how successful you are at removing water stains.
Giving you my best,
Tom
P.S. Don't bother with Turtle Wax, unless you need to work on your arm muscles for a year.
