Yes, I'm pretty sure it would work. As for the risk? Maybe that mystery 1% is the magic bullet to make all films come out perfect! Ya, Right! I would not even think of using it on something that is, so called, important. Luckily I've still got some more work to do on my FX-37 project and that will keep me busy for the next two evenings. Then Friday or Sat. I'll get a chance to run down to the local drug shop and see what they got. Sorry for the bother, but I just had a curious mind I guess. JohnW
