The biggest challenge was removing the excess without absorbing away the polish in the engraving. What I found to work best was to tap the polish over the engraved area and then wait for it to get to a thicker consistency before rubbing it into the engraving. When you remove the excess, be sure to use a nail polish remover that does not contain acetone; acetone can damage some finishes on guns.
