Hi Randy,
You don't need to goop up the threads, just liberally coat them. Yes both the plug and the breech threads. But just coat them. I take a q-tip and apply some to the q-tip and then the threads of the plug and the breech. Does not take much. Never have had a problem.
Also, any anti-seize high temp lube will work just fine. I ran in a great deal of four tubes of Birchwood Casey Choke Tube Lube. Works excellent and I'm set for the next 4+ years or so.
When installing, don't reef in the plug just snug it up.
Periodically every 7-10 shots or so,loosen and then re-snug the plug.
When you remove the plug, then you need to re-apply anti-seize lube.
