What to use to paint truss rod hole black?

[pfrank]

Hello, I'm doing a fender clone neck for a strat, and have an unfinished, maple/rosewood neck.  I will be spraying nitro cellulose lacquer, the stuff StewMac sells.

I want the black oval painted truss rod hole on the headstock ala fender.  Given incompatibilities between nitro and many paints, and the fact that I barely need a couple drops for the job, what's the best way to accomplish this - and is it done by hand with brush, masking off the wood in the oval shape?

thanks for any tips or ideas.

The one I have, it isn't paint but a black plastic sleeve insert.

ok thanks.

So...to those who might be able to answer the question - if i wanted to still go ahead and paint it, what is the best option - adding black pigment to my nitro lacquer?
