I just dug this thread up to Give Credit where it is Due, Mr Sideshow Definitely knew what he was Talking about with this Permatex #80632 Thread Sealant with PTFE, This Stuff Definitely WORKS to keep a Nipple from Seizing up in my Sidelock Muzzleloaders, This appears to be some Really Good Stuff, No More Breech Plug Grease for Me! After 10 Shots the Nipple Broke Free EASILY, and the AMAZING part is i was able to Remove the Nipple with my Thumb and index Finger NO PROBLEM, I have NEVER EVER been able to do that with Breech Plug Grease, I have to Stay on the Nipple with my Wrench all the way out to last few Threads. I look forward to testing this Stuff More in the Near Future, I will have to Run up and Grab my Buddies Knight Bighorn in-line so i can test it on a Breech Plug that is NOTORIOUS for Seizing after a Shooting session with Real Blackpowder
A can of this Stuff could Very Likely be a Lifetime Supply, especially with little No. 11 Nipple Threads
To those that might not know? On a Breech plug, I would make SURE to get a Coating of this Stuff NOT only on the Threads themselves, But the Sealing Nose edge, and forward Unthreaded portion of the Plug (Red arrows) There is a Brush Applicator in the Bottle That Would make this EASY to do
