This is how the PDLC film looks after a few winter months. I had installed it back in December. The film is totally stiff, it does not adhere to the plexi-glass bottom any more. Not sure if the extreme of temperatures destroyed is, or, if the UV-rays damaged the various layers of film. In any case, the PDLC film is in such a bad condition that there is no hope of refurbishing it in any way. Therefore, I consider this as a total loss. Let me know if anyone of you were more sucessful.
