Anyone try this yet? I mixed it at panel-wipe strength per the label and gave it a shot. Don`t have shade at the house and water is coming in at 223ppm turbidity from the city (outside hose is not filtered thru water softener ). Have not tried any dedicated products for waterspots, but this did a decent job on both glass and paint. Granted it was just washed and I wanted to prevent sun baked spots.
