It should have three bond, yama bond, honda bond or whatever you prefer, they are all the same. Give each side a thin even coating, allow a few minutes for it to "tack up" and stick the two halves together. I have used 3 bond, and never had any problem with it leaking, its one heck of a seal! It looks a lot like grey silicone, but dont substitute it for anythine else!
