Universal Anti-Fog Film

I tried this when I got the photochomatic shield for my Neotec 2 and it had lots of little scratches in it. Seller promptly replaced it with a new one that was much better. It is a very thin piece of plastic that sticks to the shield not like a regular Pinlock. I did end up getting a true Pinlock for myself and it does fit perfectly in their shield. For my high humidity area this is working better.
