theres this stuff called vibratite....works better than Loctite (thread locker) its not cheap, but a little bottle goes a long way... I use it on cowl screws, hatches....stuff that i remove more regularly. It lasts about 20 cycles unlike threadlocker which is a one time use... You simply brush it on, sparingly though if you put too much, especially on small bolts you'll have a hard time screwing them in
