I have the UW and it has always been watery as well, but still seems to work fine. Offers a couple weeks worth of protection on my daily driven vehicle in a location where it rains very often. Not sure if I should expect more from an over the counter product? But I didn't think it was terrible. I just got JaxWax liquid paste now which is on an entirely different level so not much need for the UW anymore anyways. I may still use it on my girlfriends car.
