The coating makes it tough. We have the same problem with helicopter windows in the Army. The trick is to find a polish kit that goes to about 15,000 grit. It will reduce the amount of haze in the windscreen. Just my experience.

I had a scratch in my Clearview shield a couple of years ago. I was unsuccessful in buffing it out by hand until I tried using a buffing pad on my cordless drill. You want to keep the speed in the neighborhood of 1200-1500 rpms. For cutting compound I started using Novus 2 and switched to Novus 3, followed by a good cleaning with the Novus cleaner. The buffing pad has to actually generate some heat before you start to see results. You must keep the pad moving or you will "burn" the plastic.

I worked on all USArmy helicopter windshields years back.
There was a kit but cant remember the name. Mirco.... ?

As a final touch one might try a Auto finishing Glaze compound.
Fills in even microscopic scratches. Its like a miracle. An outer coating is needed or else it will eventually evaporate. No idea here. On paint a carnuba wax works.

If you buff it out, put some UV protectant on it as well so it doesn't haze from the sun.
