I was just about to recommend Rain-X. I use it on my glass Ranger windshield. I use it on my cars. I use it on the leading edge of the hood and grille during bug season. It worked really well on my 737 windshields. Been using it for 30+ years.
Over time it will craze polycarbonate material but a way to minimize that is to put a little excess Rain-X on a rag and let some of the solvents evaporate. Give it 30 seconds for most of those to go away and then apply it to a clean windshield. If you haven't used it before, it'll look like oil because that is essentially what it is: silicone oil. Grease the surface up good. To keep a layer that will last a couple months, don't wipe off the excess, use a hose and wash it off. Running water is all you need. A bucket will do. Then, don't touch your windshield unless absolutely necessary.
Glass is unaffected by Rain-X but Poly windshields in utes only seem to last three or four years anyway, I'd use it rather than putting on a wiper.
Tip: If you use it on your car, try to avoid using the wipers if possible as it degrades the coating. You can help by wiping your wiper blades with the rag of Rain-X when you are done. All Rain-X needs is a little wind or vibration and the water completely sheds.
