Put window dark tint on our glass cabin
windows to keep the heat down in the cabin
. This worked great. Got the film at a local automotive supply store. Directions call for spraying a water
and soap solution on the window (inside) and film and apply film on the window. Position then squegee the water
out (sponge works well). You have to work any bubbles out from the center towards the outside ends. After about a year the film started to shrink a little at the edges but not bad. To remove you scrape with a razor blade and wash window off. Do not use harsh cleaners and only soft cotton cloth to clean otherwise it will get scuffed up and optics will be deteriorated. Try a small piece first to get the hang of putting it on.
