Thanks Jaka, I did not know that bad reaction between plastic and Loctite.

Blue Loctite cures when confined in the absense of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.
Hence; no much locking effect if the compound is applied outside the male-famale thread interface.

Note that CA can be dissolved by nitro fuel.

In addition, anything on the expossed thread only will not avoid the bolt to loosen at least a little.

Some silicone caulk over the thread and the mount, or a counter nut on the expossed thread may do the trick better than CA.
