Frank,
When restoring micrometer sextant scales, I scrape out the old paint with a scriber under magnification of about x 7 to aid my aging eyes. I then fill in the graduations with acryllic poster paint and almost immediately wipe it off again with a barely-damp cloth. For small areas, just licking the cloth is enough. The poster paint is very quick-drying and it takes very little practice to find out what "almost immediately" means for a particular paint. If you get it wrong and the paint doesn't wipe off the face of the instrument, simply use a wetter cloth and wipe harder. Once dry, it is reasonably waterproof.
