Okay if I chime in? I agree with everything that has been said, however What temp you heat your sinew at I think is very important,just as if you get sinew too hot it will turn up on you. My guess this is what happened along with possibly and some others,such as been said clean and I score the surface a little , And put a prime coat on first, I use a old arrow to smooth the material down, then one more light coat as soon as the tacky state is gone ,done too soon it will lift and gell and glob. Too much glue it will do also. And when you are done it is going to make some cracking noises at first, sometimes.So much for my two cents. Denny
