I´m asking because we have six platters using PTR´s now and I´d like to try FG on one of them, using media cleaners. Furthermore PTR´s are the recommended way to go from our service company, and I don´t wanna be made guilty for other people not to be able to use their cleaning rolls. Please no rant now about PTR´s only beeing usable for clothes. When used on every show and cleaned thoroughly inbetween, I´ve found them to do good. After beeing away from work for 2 - 3 days, the prints are quite dirty again. (I have a hard time convincing people to use them) I know, you ranters will say the prints will be better off if they don´t, but if you saw the state of our own company trailers, THX trailers and other stuff that go on every show......up to last month they were cleaned at best once a week, and they´re really dirty. I learned just a month ago that they should be used on every show! The company actually teaches to use them only once in a while. And that they need not be changed for new ones!

Does FG has any effects on other protective treatments like Gelflex, which is used for some prints in Sweden?

How is FG on the environment? What chemicals are in it? Our company has an environmental policy. And my conutry has environmental laws.

I recall that Brad has a Material Safety Data Sheet (MSDS) available to answer your other questions.

Brad, can you also say anything on the last two questions in my first post? Also do you know of any Swedish users you could direct me to?

What is Gelflex? Is this like 3M PhotoGuard?

Since I only have 6 cleaners at a 24 screen theatre, each print only gets cleaned for a full day once a week.
While its not running, you can see it start to dry and it will look like there are splotches on the film (at least when its during a black spot with no picture), but it does not show up on screen.

If you are seeing "oar (oil?) splotches" on the film as it dries, you should definitely reapply. I suspect you might also see some of these splotches as "mottle" on the screen during light scenes.

Almost nothing sticks to PhotoGard (3M ScotchGard Film Protector). You even need a special splicing tape to be sure the splices stick:

Gelflex is manufactured by Rotebro filmservice, who are, (I´m sort of qouting from their website), "the leading company in the Nordic countries for restoring and preserving film. (.....) Gelflex is a treatment that makes the film anti-static and protects it from scratches, drying and dust. It also gives the image better brilliance."

Sounds like FilmGuard, though I think it is permanent, and they treat it in their laboratory. Sometimes we get prints from the Swedish Film Institute (SFI), and they are often treated with Gelflex. I don´t know what´s in it.
