[B][I]just came back from walmart,didnt have the green or the red film.had plenty of greys and black.found this in the auto part of walmart.im assume this film would work.just want to cut it down to size and use a little velcro,to flip back and forth when the needs arises.so maybe ill check the local auto parts store to see if they have any green or red film.anyone every use this type of film?and if so,does it work good for not killing you night vison?[/I][/B]
