Thanks OZZ,
I was worried that if you didnt get the film stretched out properly and had wrinkles in the film, these wrinkles may eventually lead to pin holes.
I saw some of this film it was a 10"x10" sheet for $29.95 US, at Rivers Camera and Telescope, I could stretch this out over the 4 inch aperture mask on my 6 inch lens cap. would the acid on your finger tips also degrade this film?
