May be for a different purpose but have used it on antennas for along time
and have never had any problems with it. Seems to conduct just fine and will
certainly let things come apart easy. Last use was on a TH6DXX, no ill side
effects, still up and working without any problems. Antenna analyzer shows
all is well.

Yes, I have used the NeverSeez conductive grease, sold for automotive
repairs, on things like car battery terminals, to resist corrosion and
enhance conductivity. It does fine there.

As long as conductivity is good, and there is no capacitance created,
it should be fine.

There are two varieties. One is a mix of graphite and moly in a syrupy solvent.
One is a mix of copper dust and moly in a pasty solvent. Either one works well
and we notice not a whit of difference in the conduction properties. In the
aircraft industry, we use them rather interchangeably to coat the threads
(lightly) on spark plugs so they won't pull out the helicoils in the heads when
we go to change them annually, on manifold and muffler bolts so we don't have to
drill them out when it comes time to work on them, and on any other thread that
is likely to become corroded into place.

If necessary, you can go to an aviation supply house (Chief Aircraft, Grants
Pass OR; Aircraft Spruce, Fullerton) and buy as much as you need by mail order.
In a really well-stocked automotive supply house you can buy it by the dribble
bottle, pint, or quart.

shared these priceless pearls of wisdom:

-I need some of this stuff for antenna assembly. Anyone know where to get
-it?
-
-For those who don't know what it is, it's a paste you get in a little can or
-tube that you smear on mating metals to avoid having them stick together
-after exposure to the elements. It's also used for soldering irons to make
-replacing tips easier.
-
-I think it's molybdenum disulfide.

Hi Bob ... I applied Permatex anti-seize to the bolts on my tower and the
boom-mast-rotor hardware. The whole works came apart smoothly after being
up for 20 plus years. The material I used between the Al junctions on the
TH-6 was supplied by Hy-Gain in a little metal pill box. Likewise the
stuff
worked great. SS hardware used on the antenna.
======================================
In the UK a very good stuff for outer metal protection is Finigan Waxoyl,
available from many autoparts - and hardware shops.
Living in a windswept area near seawater ,hence with a lot of salt spray ,I
use it on all bolts and nuts and galvanised metal clamps etc.
Of course it is NOT suitable to make galvanic contact between (dissimilar)
metal parts.

This is definitely a "me too."

Waxoyl is excellent stuff - a blend of wax and oil (surprise) plus
corrosion inhibitors that really work. I recently pulled out a rotating
pipe mast that had been sitting in a ground socket full of Waxoyl. 10
years of condensation had turned it into more like an oil/wax/water
emulsion, but the bare steel came out looking like new.

In more normal use on nuts and bolts, the oil dries out and the wax
coating hardens, so it also acts as a pretty good thread-lock.

Don't know if Waxoyl is available outside of Britain... but if it isn't,
it should be!
