Sorry, but the first bit of your post is wrong-ish, in Engineering world (not models here) a nut and bolt is not a permanent fastening, and should never been used as one, for a multitude of reasons. You put a nut and bolt or stud and nut etc where you will need to remove in future for 'some reason'

Anyway, I would recommend for use in RC cars Loctite Blue, you can even get it in a no-mess 'pritt stick' format!!

It facilitates easy removal when required.

I only reccommend on past experience of non RC applications (before I get shot down) but have never had a screw come loose on the durango lol!
