So why would we want to risk corrosion damage to the aluminum by including a
copper filler metal just in case the grease _does_ happen to be the "leaving
kind"?
73, Eric  N7CL

Eric good points. The reason I heard was that Noalox does go away after a
while, whereas SS-30 does not (at least not in 10 years here in Colorado).
SS-30 must have the right grease base. It doesn't evaporate or deteriorate
easily. The manufacturer says it won't dry up in storage. It's temperature
service rating is -65F to +1800F and is used inside of Jet aircraft engines
and other real harsh environments.
