I'm definitely quite keen to trying of these though as living close to the Mendip Hills, our water is very hard and will spot on almost any surface.
To higher a flow rate & the resin won't do it's job, but running a pressure washer on it's low flow rate should work, but you would need to take a sample of the water to check it's ppm. Giving a final rinse with a open ended hose will walk the water off the panels leaving them mostly dry.

Scrannel what mixture of it did you use? Teaspoon per gallon?

On a black car I used about 50-50 to 100%. Vinegar is not terribly acidic (which is why you can drink it, of course). Try a single spot if you want using 50-50 or even 2/3 water and gently brush it with a Q-tip, just to test. The chances of it actually attacking clear coat are extremely low. But make a test area if you want. We get a lot of water spotting in So. Cal from lawn sprinklers hosing down cars and then having it bake in the sun.
There are plenty of water spot removes on the market as well. Such as:

To avoid them in the first place I remember a few years back when the SE of England had droughts instead of floods, that the guys over on RRSport were all using de-ionizers to rinse their cars. You can buy de-ionising filters that screw in between the tap and the hose. They reckoned their cars stayed cleaner longer and also they didn't suffer water spot marks. Don't know why it works and have never needed to use one myself as we have soft water in Scotland (and it hasn't been passed by five strangers before you get to use it!)

Tim, you are right about the de ionised water bit, detailers tend to use filtered water, but the OP didn't have that luxury sprinkled on him.
