Awesome product: Rain-X

On a recent trip to Oregon I applied Rain-X to our windshield for the return trip and what a difference it made. It causes the water to bead up rather than puddle and at speeds of over 40 mph or so the drops slide up the windshield, merging to make larger drops, that fly off the top and leave a clear path behind. It means you do not need to use your windshield wipers at all.

This is such an amazing product, I am amazed more people haven't discovered it.

[And no, I don't have any stake in the company.]
