I always keep several bottles of dollar store nail polish around in the
shop/shack.
I use it to mark vacuum tubes in my Drake stuff, among other marking
requirements. Especailly handy to mark/color code PL-259 connectors.

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.
