Those little push nuts go on and stay on tremendously well...once.
As much fun as I have prying them off shafts, I've hardly ever seen them 
fall off on their own.  When they did they were invariably mangled on 
installation, split, or mangled on removal and reused.

Generic thread locker or keyway locker would fit the bill well if you really 
want something on those push nuts.

You might also want to look at Locktite Blackmax.  It's been some years 
since I used the stuff, and I'm not 100% certain the current formulation is 
what I used to use.  But the stuff would stick everything together, and was 
flexible.  We used to do things like glue broken belts together with the 
stuff.
