Yeah. That was probably my brain aneurysm acting up. Probably conflated WD40
and DC4...

I think you mean DC4 which is dielectric grease. The chemical composition
is probably similar to DC111 but it isn’t as stiff. DC111 is basically a food
grade lubricant for rubber valve rings. I suspect that plumbers grease that
you buy at a hardware store is similar stuff. DC111 probably has silica added
to make it thicker.

If you like the single use packets instead of 5 oz tubes, I think these are
probably the same thing:

I always used DC-40. I bought it at the airplane shop.

Do you lube the O rings on your licensed antennas? I have seen some
where they didn't and the O ring cracks apart, potentially causing water
ingress.

Most of the big names include a small pack with the radio or dish. I am
struggling to find the exact product. I have heard people say that you can
just use Vaseline, but the Internet says the petroleum will eat the rubber o
ring within about a year. I see dielectric grease also being reported as being
used, but it will supposedly also melt the rubber.

Most are recommending Silicone Grease. The only silicone grease that I
can find locally is "100% pure Silicone Grease" that is "Spark Plug Boot
Grease". I figure that spark plugs boots are also rubber so this is probably
the stuff, but it is also listed as being dielectric, and it contains
polydimethylsiloxane.... whatever that is.

Does anyone have any recommendations for what I should use to lube the
O-Rings on my licensed backhauls when they do not include a tube of whatever
they usually include?? Anyone have any stories about things that did not work
out?
