Oh, I'm all for using loctite for a suicide. But you are incorrect when you say it will eventually cone loose. When you rotafix, you apply a force far higher than your legs could. The math is actually rather simple. But for an added belt & suspenders, loctite will certainly increase your factor of safety.
