[R-390] grease

[rbethman at comcast.net]

Dan, and the group,

I obtained two or three VERY large tubes of Silicone Grease from a Xerox copier repairman.  These are about a pint or so in size.  I couldn't tell you whom makes it, I think there is a "xerox" part # on the tubes.

As to removing it - I also obtained a bottle or two of degreaser from the same tech.  This item has since been consumed.  I got these items about ten years ago.

He even managed to mess up one visit.  He left behind a vacumn cleaner that fits in a tool kit.  I hung on to it at the office for over 7 months, but I never saw him again.

So I became the owner of it when our Org moved.  It is VERY convenient, about 12" X 4" X 8" for the entire system, bag, hoses, motor, and accessories.  Now I only have to find bags for it, or "make" some.  VERY nice for cleaning out a chassis!
