This is something that makes sense. (That’s why it took me 2.5 years to figure it out :()
By dabbing whiteout on both the nut and the spindle, you can see if your nut has come loose when they aren’t in the same place any more.
However, if your nut spun exactly 1 turn, you may not be able to tell.
Great idea. I am not always the best at keeping an eye on that. THat should make it much easier.
Periodically checking your uni is a good idea. Last weekend I checked all our Uni’s and I thought King Muni-Man’s would have the loose nuts (he rides the most) but it turned out that my daughter’s crank bolts needed tigtening instead. Perhaps his light weight doesn’t place much strain on the cranks.

I just read the subject line, and thought “Ouch.”
ive heard alot of complants about Monty cranks falling off and never being able to get them tight enough to stay on,are you have this problem?
OK, JF is silly sometimes.

My fell off after a few KM’s, but I’m thinking that was just the bed in period (I can’t recall if I retightened them after a few clicks, so I mustnt’ve)
Apparetly it’s only the short Monty cranks (I have the 158’s)that don’t seat on the spindle. I just got back a few hour ride with many drops, grabs, and the fun stuff, and my white out remains intact 
I’m putting shorter cranks on my 29er so I can do the Unithon in under 24 hours. I assume the aforementioned and aforepictured nut is the thingy that holds the cranks on?
Shouldn’t you have an opaque plastic cap there? That way the rain won’t wash away the white out? Anyway, thanks for showing all of us what’s behind those plastic caps.
I ordered two cranks and two crank pullers (I know I only need one). I think I’m supposed to get Loctite, but I’m not sure which color. And white-out (white).

Those plastic caps, although useful at retaining the nut if it falls off, get in the way of checking and tightening. I throw them away, as I’m always changing cranks around.
I thihnk that white out is pretty solid there, if not, I have more
You want #272 high strength Loctite (it’s red in colour, but every Loctite bottle is red, so look for #272)

Finger nail polish would probably be more durable.
Dust caps would be needed to make anything survive for a long time.

I use a black Sharpie to mark the spindle and nut.
only Royal Canadian Mounted Police are allowed to do that!!!,turn yourself in now!
