I've been tying some flies with epoxy and used them for the first time this summer. I noticed that after a while of the fly being wet, some of the flies or parts of the epoxy turned opaque or white and got gummy and could come off. After the flies dried, the area turned back to normal. I looked at my epoxy and it says that it is water proof. Anybody else ever have these problems? If you don't, what epoxy do you use? Also, the epoxy I use does not make a super hard head. It's kinda rubbery. When it is tapped against metal, it does not make a clicking sound unlike some flies I have gotten in swaps which make a clicking sound when tapped against metal (like glass would). These swap flies are much hader than my rubber like epoxy.
