Which one adds more performance value to the glass? Sunscreen or dyed window film?

Nice video. Very impactful. I would chop this up into a 1 min video and post on social media ( Instagram)

So a cheap sunscreen will end up blocking more IR than a color stable dye film? That's new.

I wonder what deodorant would do? Rub a stick of degree on there and let us know.

If there's a point to the video, which I just slid through to the meter reading, is that dyed film does nothing for NIR (Near Infrared).

 

The Sunscreen blocks 95% of the NIR, which makes up 48% of solar energy from the sun. All of the sun's energy converts to heat (far infrared) once striking and is absorbed by an objects surface.

 

Law enforcement agencies use Dyed limo tint on vehicles they use to do their IR camera surveillance after dark for the very reason that dyed film does not block IR. Dyed film is antiquated film technology that still serves some purpose out there.😁
