. Mixing grease and loctite compounds isn't necessarily a good idea. Sometimes a little extra thread filler other than loctite can work via teflon tape. YMMV.
Wrong. You can't "prep" a BB with loctite. You can preapply some other sort of thread locking material, but it's just a gap filler, not an adhesive like loctite.
