    Re: Instrument Engraved Marking Restoration - Help
    From: W F Jones

    Thanks for sharing your experience with the group. I don't have a bottle
    of the acryllic poster paint but my wife informs me it is common enough
    and easy to get.  I plan to begin my search a little later this PM for
    some.  Another suggestion posted uses waterproof India ink and I may
    have a bottle but it doesn't explicitly label it as waterproof.  I have
    a laundry marker pen and a Sharpie to also try.  I vaguely recall
    someone telling me years ago that engraved lettering/marks on metal were
    often filled with jeweler's rouge and sometime sealed with a clear coat
    of something.  I have a few ounces of rouge but the pale green color
    rules it out since black is needed.
    I have constructed some simple test strips (water resistant paper) which
    will be soaked in a water bath for a minute (ummm, maybe a NY minute) to
    see what happens.  The test strips will first dry for at least 24 hours
    before immersion.
