Has anyone tried this? We need to clean the sound reels at a local large format theatre and unfortunately this is somethng that I can't experiment on. Dry Media would be another choice that we can use for this.....also wondering how the Filmguard might effect the head gaps...would it clog them up and would it reduce head wear. Am installing a new 6 track head tommrrow on this dubber and was curious if anyone else has actually Filmguarded mag stock......

Others have reported that while using FilmGuard on mag prints, you'll reduce head wear and have less (or no) oxide buildup.

FilmGuard is safe for use on mag prints.

I've never done mag fullcoat, but I can assure you that it works magnificently on the 70mm 8mm magnetic tracks. I would still recommend the Kelmar cleaner for application though.

Mark,
Should not be a problem if as Film Guard is already being used on 70mm mag stock with OK results.
When I was a Technical Manager for Telstra (the only real Telco in OZ) some of the larger telephone exchanges had multitrack recorded voice announcing machines (RVA's) that were used to insert a 10 sec message on customers lines who required a spoken message as to their new phone number.
This thing was huge with 12 tracks and it ran continuosly day in day out. It had a 250mm diam aluminium drum with a 4mm thick full coat over that as the recording medium and all 36 heads dragged themselves over that as it slowly rotated. (Was a Record, Play and Erase head for each track).
A big felt pad rubbed upon the surface and that pad had to be kept moist with Silicon Oil otherwise the reproduction was crap, the thing would squeak like you would never believe and the heads just wore out in super quick time.
When properly coated with silicon oil it positively glistened with the amount of oil needed to keep the thing/s running OK.
So a little bit of Film Guard on full coat stock would be a very good thing in keeping the heads clean and stopping the inevitable chatter that occurs when things get a bit dry.
