I've used Tru-Oil, poly spray and Massey finish(2ton epoxy thinned with acetone)on sinew backed bows. My Medicine bow has all three. Shellac will stick to it. You could give it a coat of shellac then add whatever finish to it you want. Pat
Thanks Pat, I do believe in shellac,was not sure if laquer would stick to shellac.right now i just use shellac.
I just made some hide glue out of left over goat, deer and cow hide, now I need to get the senew.
I asked the meat market if they had some cow tendins or backstrap, not sure if that will do,I don't really see any difference.
Thanks for the info.
