I don't even run my fingers down the film. I run it through the wetting agent rinse and hang it up. I very seldom experience drying marks and if I do, well there's nothing a little IPA can't wipe away. I have a squeegee but a very wise man who got me started on film told me never to use it.
I have experienced how easily film can scratch so I would never use one. I just wonder every time that I see the thing just sitting there why I don't just bin it. I am just amazed at how something so ultimately unnecessary manages to survive and often wondered if there was anyone who actually used them.
