[R-390] grease

Bob:

So yours is wet (what a line) Possibly I was quick off the mark as the graphite lube that I was referring to is/was powdered and when applied resulted in overspray!

Actually, I have NOT found there to be a migration problem.  As with ANY lubricant used on the gear train, "Just a little dab will do ya!".  The gears AREN'T making "wild" rotations of high RPM.

Since this particular lube is wet when applied, it stays where you put it.  I use it, and find it hasn't migrated in over 5 years.  The "train" is smooth as silk.  This same tube has lasted for MANY uses for about 12 years, and looks like it will last at LEAST another dozen or so.

It is about a half or three quarter ounce tube.

I only apply it to the shaft to gear locations, NOT on the teeth themselves.  In that location I use a Silicone Grease.

No issues with it or the other getting into modules!
