[ARC5] Tropical Coating

[Gene Smar]

Jim:

     What your areprobably seeing is what is known as MFP - Moisture and 
Fungus Proof - coating.  It was applied after assembly to all WWII and 
Korean War vintage milrads.

     Some time back there was a thread hereabouts that described the exact 
components that went into the coating.  IIRC, it was bees wax and varnish. 
There were several URLs for references to the mixture in some of the 
postings at the time, but I neglected to bookmark them.

     Can someone out there refresh our collective memories about the 
references?
