I have been experimenting with beef suet on bows. The only thing I dislike is that it never seems to really "cure" like other finishes. The suet seems to attract dirt which is hard to just wipe off. Water beads up and doesn't penetrate the wood, which is good.
Maybe I am doing something wrong. I wish I could figure it out because I sort of feel like I am cheating using modern finishes on some of my more primitive bows, but try-oil leaves such a nice, easy to maintain finish.
