I have experienced problems with water spotting with the new Ultimate Wash & Wax. No matter what I do (wash in the shade, keep the car wet, etc), the water spots appear. These spots actually look different than those that appear with ordinary wash shampoos: they look like tiny droplets. I presume that this is somehow related to the dispersed wax that UWW leaves behind.
As a general rule, I always follow-up a wash and dry with a quick detail wipe, precisely to eliminate any spotting--and there is always spotting. I haven't yet been able to figure out a wash & dry technique that doesn't leave behind water spots. The water here in Roanoke has a high mineral content and apparently I can't get the car dried quickly enough. I eliminated the quick detailer step with Ultimate W&W because I didn't want to remove the "wax" left behind by the shampoo. Well, I've learned my lesson.

To the original poster: I understand your frustration. The water spot problem is probably not caused by the Gold Class shampoo. You may be able to correct the problem by changing your technique (wash the car in the early morning or early evening, keep the car wet throughout the wash process, etc.), or you may find, as I have found, that you need to either add a lubricating aid (Last Touch, Quik Detailer, or perhaps even Ultimate Quik Wax) to your drying method or wipe down the car with a quick detailer immediately after you have dried it. Good luck!
