Review on Enhance Your Windshield Cleaning with Rain-X White RX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml by Christopher Clearfield

I usually use the original RainX, but I wanted to try it. There is a gauge on the side of the bottle so you can see how much you poured into the tank. So it's easy not to bet too much or two less. After only a few targeted waterings of the pane (3-4 seconds of spraying) over two days, the next rain dripped off the pane as if I had applied the original RainX. I'll probably switch to that from now on. no more sore elbows from rubbing the original RainX.
