No we don't Loctite the barrel nuts. Sometimes they are hard to take off as through time they sieze up a bit. We use a cheater bar to loosen them.

Leverage was not the problem.
I found a small amount of an unidentifiable alien "red" compound underneath the barrel nut of my upper. It was placed where the locating pin is, though small, it was enough to force me to spend an hour grinding off the surface of the barrel nut under the delta ring until I could finally peel the thread off.

A small amount of Loctite is used on the barrel extension index pin but not on the threads of the barrel nut.
