I made a 2 pc trade bow a few years back, had it sprayed and drew it a couple times, heard a tic, and found the glass wrap had cracked at the top edge.
You can't send a trade bow like that, so I put it on the shooting machine and drew it to 30" , turned my head and dry fired it. Nothing!
So I put it on back burner, made another trade bow and shipped it.
Later I re did the sleeve but have yet to grind it back to grip shape.
Anyway I think the phenolic did it's job on that one!!
