I had one that started peeling, I just run the knife under it carefully until it was all off. I dont know what kind of glue was on it, but it was black and hard as a rock, it took me a long time to scrape it off.....when I got finished, the bow was in bad shape. It looked like they had used sixty grit sandpaper on the limbs, they were deeply scratched. To fix this, I sanded them with 600 grit wet sandpaper until they were smooth again, then applied about three coats of turtle wax to even out the finish. When I was finished, you had to really look at the bow to be able to see the flaws. The stuff will come off, but it takes a while.
