I covered the windows in my garage with the stuff. I chose to leave on the white protective film to prevent people from peering in but still allow a bit of natural light to shine through. The film peels right off. If the Lexan is intended for a door or window that needs to be a little more attractive, it’s certainly possible to use smaller screws, or even ones with little decorative covers. In most cases its purpose would be to prevent an easy reach-in, so it doesn’t necessarily need to be affixed with so many screws that it looks like part of an aircraft.

I got this 1/8” sheeting at TAP Plastics in Seattle. The material is not cheap, but they sell it for quite a bit less than any vendors I found on the major online marketplaces. TAP even cut it down to size for me. Some of these products tend to yellow and turn brittle when exposed to constant sunlight, but TAP’s product is UV-stabilized and supposedly doesn’t do that. Still, it does lose integrity over time and after 20 years it might be worth replacing it. And one thing you have to watch out for is scratching. Though breaking it is a real challenge, scuffing it is easy.

This is one more useful tool to consider employing as part of your overall home security strategy.
