It's a liquid sealant, like pipe dope, that has teflon in it. Advantage of it over the tape is. It gets into the threads a little easier then the tape. It is easier to use then the tape too.

I wouldn't use Lock Tight on the plug. You might want to remove it. Also, it is a pipe thread, which is tapered, and doesn't need the locking of Loktite..
