[R-390] grease

[rbethman at comcast.net]

Yes, as originally stated - "Anhydrous Graphite".  It IS in solution.  I don't remember "exactly" with what, BUT it is.  It applies "like" grease out of a squeeze tube.

The spray type lubes NEVER get applied in ANY of *MY* radios.  I do not care if it is molybdenum disulfide, OR silicone.

If you ARE spraying - YOU don't know WHERE the overspray goes!  I apply by toothpick, "Q-Tip", or other VERY directive means.  Sometimes syringe and fine gauge needle.

An for Lord's sake - STAY AWAY from WD-40!  It is NOT a lubricant!  READ it carefully!  The "WD" stands for "Water Displacer".  Best and almost ONLY use for THAT *crud* is in locks that are exposed to the elements.  I.e., on sheds, trailers, and perhaps auto door locks after exposure to heavy rains.  Always follow WD-40 up with a REAL lube!
