Whoa! Three cheers and 5 stars on Tripadvisor for simply _mentioning_ green Loctite. Truly, it is the nuclear option for thread-locking.
Suggestion: a whole tech article on thread lockers.
Here’s one: for threaded BBs, Loctite 567 pipe-thread sealant. It hardens in an anaerobic environment as usual, and has Teflon in it. I’ve been using it for 20 years, starting on a Ti frame. It’s great at preventing dissimilar-metal corrosion.
In its hardened state, it’s a little tougher than dried toothpaste and has a bit of pliability. I’ve never had a problem removing a threaded BB with it — always used copiously.
Cleaning out the female threads is not a horrible job — by chasing around the thread grooves with a dental pick (or bent nail in Vise Grips). A small, very stiff wire brush is helpful
It may be the cat’s meow if used on pressed-in BBs as well; I’ve never tested that application.
