Apply a product called "Liquid Glass" to the windshield/screen, a couple of coats will last longer. It takes a very small amount AFTER you've cleaned the screen nicely. Goes on easy and removes easy. It's a car polish/paint protector, which is it's main use. I've used it for years and it makes an excellent polish coat after washing and claying, then Liquid Glass, and for the wet look then wax.

Years ago I tried it on my windshield and it worked wonderfully, better than RainX and lasts longer too.
No need for wipers at all once above 40mph, for best effect. Rains just rolls off the sceen.
