Nail polish is viscous and readily available, and easily removed with a 
solvent if needed. It's also not too brittle, so it won't crack with 
small loads. Also because it's solvent based, it tends to work well on 
fasteners with an oil film, because the oil goes into solution with the 
solvent. You can also do color coding - red for this year, blue for last 
year, or bands or whatever.

Probably any lacquer or solvent based paint would work.


I'm not sure I'd go with an epoxy - too hard to remove if you get too 
much on. And, some don't stick well if there's an oil or grease film.
