Sorry to hear about your experience. We do genuinely appreciate all feedback. Please understand that water spots come from water (and the various minerals in it) staying on the surface long enough to etch into the paint. Typically the only way you would get water spots when using a good car wash is simply by allowing water to dry too quickly on the surface during the washing process. This can of course become more problematic if you have a hard water source and/or you are washing your vehicle in hot temperatures. Feel free to reach out to our Solutions Hub via our website to discuss this issue or anything else at all.
