What foil to use on glass and/or acrylic

[Blauenfeldt]

I have been looking around on this site, but I can’t seem to find what kind foil would be good to use.
Can those who have tried foil, describe what their experience is, and what kind of foil they used eg. what transparency it is, vendor, and name of the foil.

The typical smart mirror film is Gila mirror window film (https://www.amazon.com/Gila-Privacy-Adhesive-Residential-Control/dp/B000H5XTKG). I got mine from Lowes in the U.S. It is a lot cheaper than two-way glass, and the quality isn’t mind-boggling but it’s not bad either. I think it’s 30% transparent but you can check that through the link. I applied my film to acrylic and it worked well enough–I’d recommend it if you’re on a budget.
