I have a small tin of "French dial enamel", which I presume is used for such purposes. I've re-done the "ON" and "OFF" lettering for the buttons on the controls for my lathe, and it seemed to work fine providing the target is prepped/cleaned/de-greased. I have not applied it to any of my pistols, but it should work for them, too.

The smearing of letters filled with paint can be minimized by using a stiffer absorbent wipe, such as a piece of blotter, backed up by a small block to keep it flat. Wait until the paint is just about dry, and add a drop or two of the appropriate solvent to dampen the medium you're using.
