Not glue, but a while back I melted some beeswax into some mineral oil with a 50/50 approx. volume ratio, making a grainy paste. I rub it on the bow, leave it overnight, then take off the excess and rub in the rest the next day. Works great and makes osage look awesome. Definitely not high gloss, more of a dull, natural shine. If you're looking for cheap, for about $10 this would last me 7 - 8 bows.
