A pad lock maker used to use a thick near dry paste paint to fill sunken dial numbers*. Perhaps you could use a similar approach. I think your better off applying paint 'wet/uncured' and removing it wet.
*IIRC some of my peers at MSOE had a college senior design project to come up with a less antiquated method.
I don't know how small it is, but perhaps a fine tipped paint pen or artists brush and a steady hand could fill the letters.
