I realize this is a tangent from the OP, but I do wonder how much of this back and forth with @bloc on RainX is a result of the VERY significant differences in washer fluids. Maybe they all work differently with the nano technology of products like RainX?Ok @bloc that helps me understand where you are coming from. I haven’t seen what you are describing, but I am going to be on the lookout in the coming days to see if I observe the same.
