If you do use threadlocker use the Blue type. The color codes are constant among manufacturers and Blue is the type that can be removed. Red is permanent and I think green will wick into threads that are already screwed in, but from what I understand once its in there it will never come out.
Just remember BLUE
Your correct about the green. Its also great for holding bearing races on pinion gears where the hard bearing race might wear away the softer pinion.
I just got a JR Vibe in for review and it came with two bottles of thread locker, red that is medium strength and green thats permanant. Go figure. It was well annotated in the manual though.
