Rain-X on our phone booths?

[CastawayRK]

Are the windshields on the FSH-E (mine is 222) Glass or plexiglass? I want to Rain-X it but the Rain-X site specifically says not to use it on any plastics or plexi.
Cheers

Rejex works great on my little windscreen, no streaking doesn't mess with my polarized glasses.

I’ve used it on my truck windshield after a thorough cleaning and it worked quite well.

I would think any good car wax will work.

This is what I use to clean my acrylic windscreen

Same stuff we used to clean aircraft windscreen when I was learning to fly.
