Thanks everyone. I have super-hard water, and currently, there's not a water spot to be found on the car, anywhere, as I've avoided washing it. I've been using a battery powered pressure washer to rinse my boat, using distilled water, as it leaves nothing behind when it evaporates. Perhaps I'll try rinsing the car with distilled water and gauge the result. It's a 100% nice weather car, and the prior owner never had it in the rain either. I put maybe 500 miles/year on it, so it really doesn't get that dirty!
