...or I need to be spending more quality time with my girlfriend. This thing isn't a reverse thread, is it? Am I doing something wrong?
P.B. Blaster is the bombdance2"PB blaster" in a spray can works wonders (let it soak overnight).
Anti-seize or a dab of grease when you re-install, as previously mentioned.
Are the SEI plugs okay? It seems like they make quality stuff.SAinc. had some problems in the past with gas plugs that were not hardened correctly and they would seize up every time you tried to take them out or the threads stripped very easy. I always suggest folks buy a G.I. gas plug from Bill Ricca or Orion 7 or someone who knows what is and is not a G.I. gas plug. Then you never have to worry about it again.
