Watermark stains are really irritating. It took me like a 20 times of washing before i was able to remove those stains and its all because of Rain X.
But i've just found a way to remove stains pretty effectively, by using claybar. It removes stains and tar from bodyworks really effectively, but you need to apply wax everytime you clay your car body. On the other hand, if you apply clay bar on your windscreen, you obviously don't need to wax the windscreen.
