apply the skins after you are done tillerin completely. no need to rough up the surface, tbIII will hold just fine on a smooth back. i put a fair amount but not enough to run off the sides of the bow while i am applying the skins. once you do one, you will say "boy that was easy". otherwise, stiks is right on also. and btw, i only use dried skins, never used them green. i figure there's too much chance to grow bacteria or something. if you stretch the skins on a board and use thumb tacks to tack it down, flesh side up, and scrape off any excess fat from the skin, it will dry in less than a week, then trim off the outside edges, cause they get real crusty, and then soak it in a bucket of water. PS, don't use the wife's mop bucket, they don't really appreciate that...lol
