I guess on a fishing fly, it doesn't matter if the nail is all stuck together on both sides but for a display fly, that is completely unacceptable by any standard. Thin cements will too easily penetrate through from the back onto the good side and ruin the nail. The hot glue as I outlined it, will not and is much stronger than the other options.

Happy Trails!
