For some reason we ordered 2 bottles of Goat Tuff when my friend opened his shop, one for him and one for me, and had nothing but problems. Fletchings and feathers wouldn't hold no matter what we tried to do with prep. Maybe just a bad batch but then he had to look for something else and we haven't been let down with Fast Fletch. It is a fast set glue and is cheaper then Goat Tuff.
