Tape off the checkering until the after the final two coats of finish. Uncover the checkering, apply finish/let set for a short time, dab area with paper towel to blot up excess, use tooth brush to remove excess from the bottom of the checkering, again blot excess finish from the gunstock and wipe with a lint free cloth. Let dry overnight, repeat above process. Should be close to the color and sheen you desire. Sorry the tooth brush is a goner after the first time. Use your wife's tooth brush.....if you dare.
