It's the green Loctite 640. That's what I always used and never had any issues...even w/ some I thought may end up leaking. https://www.amazon.com/Loctite-37424-Strength-Retainer-6-milliliter/dp/B0002KKTIGLike Scully said, Indian Head works great. I've seen them put in using a can of spray paint and that works too. I'm sure there's other stuff people have used successfully.
