Hear, hear! I just got my first bottle about two weeks ago and I have the same questions. I just got new PTR's and they didn't come cheap, so I don't want to ask for a media cleaner until some time more has passed. So far, I've applied FilmGuard to a few policy trailers. On the first one, I did one wet pass and a few dry passes to soak up the oozing. The others were easier because I used a new wipe with less FilmGuard than the first one. For the trailers, I used Webril wipes. As far as the features, I'm not having much trouble with dirt on-screen. I really just want to stop all this shedding that's happening. So I'm practicing with one movie. I wiped down the edge of the film (as it lay on the platter) and then the next day I rewound that movie with track down so I could then wipe the other side. For these applications, I used a cloth shop rag because Webril can sometimes get caught on splices, leaving cotton bits behind. I had read about the overzealous manager who used FilmGuard to clean the platters...prints got tossed...so I decided to play a full day with the freshly coated edge up so as to avoid any chance that it would transfer onto the platter. Maybe this was overkill, but I really didn't want to have a catastrophe on my hands...they'd never let me order or use FilmGuard again. ------------------
And, hey! Let's be careful out there. ~Manny.

Since Kodak introduced VISION Color Print a few years ago, shedding/dusting is greatly reduced. As John Wilson noted in another thread, there still are some other polyester stocks that shed and develop significant static charge. Trailers and ads are sometimes printed on these cheaper stocks. Be sure you are not using excessive gate or intermittent shoe tension, and that you have the latest projector upgrades:

In response to Jerry's comment about the potential for lint using the Webril Wipes, I haven't found lint "hairs" per se to be a problem. What can happen, though, if you use a pad to the point where it shows actual abrasion and wear a thick cement splice or a torn sprocket can pick up a small tuft of the material. The remedy is simple, though. Aside from using tape splices and repairing or notching torn perfs just throw the pad away before it starts to show wear. Using both sides of the 4" x 4" pad (sorry, in mistakently put 2 x 2 in my earlier post), and then opening the fold and reversing it you effectively get 4 surfaces, and that should be pleanty for a full feature application. Afterwards, you can still use it for cleaning the gate and general projector "hygene". As a collector, I look to Film-Guard for its wet-gating properties on well used prints as much as I do for it's cleaning properties, so applying a bit more than actually recommended isn't a problem to me.

I was showing 'The Edge of Love' this evening, and whilst inspecting the other day had noticed some marking on one of the reels, so used it as an opportunity to try FilmGuard.
I applied it whilst rewinding the film at about 2x projection speed on our tower - simply got one 10" Selvyt cloth and gave it about 8 sprays, then used this for half the film (three reels).
I'm not 100% of the effects of FilmGuard on the markings, because I only have the facility to show the print to the audience, but I think our sponsor's trailer looked better than usual, and I'm sure FG helped remove traces of other people's chinagraph, fingerprints etc.
The cloth was pretty dirty by the end of the operation!
The one thing I don't know for sure is whether my 'dosage' was right - when breaking down, reels 6 and 3 were definitely still wet, with the others looking clean, but dry. From all the posts and literature available here, I get the impression that the print should *look* wet, but should that be 'wet to the touch', or just 'glossy'?
On a side note, does anyone pop a note in the shipping case to the effect that FilmGuard has been used on a print? I think I will - seems sensible to save someone who doesnt know about FG getting unnecessarily concerned by what looks like a wet film... :-)
