Totally impressed with the product I received from Photodon
... https://www.photodon.com/c/LCD-Protective-Films.html

They have screen protectors /anti glare / privacy shields for a good price (custom cut six 9H hard screen protectors for me for $12 plus shipping) I got the 9HO - this was not a film but a plastic sheet about as thick as paper , were crystal clear when held up to a light, after installing them on my off road camera lens you cant see it, I rubbed them hard with a cloth and no swirl marks or scratches just like glass.

They can also make a custom one in any size to 82" diagonal
