This cement will do about anything you want depending on the consistency that you let it get to. It will put an excellent poxy back on nymphs if you let it get thick. It will keep a compara dun wing standing up if you treat the base with a medium consistency . It will penetrate the head of the fly if you keep it thin. I don't recommend it as a pure head cement though as you must consistently keep it thinned. However as an all around cement it can't be beat.
I bought this cement because it was the only kind they had at the Hamburg, PA store. It worked fine for most flies but after tying a few with the Otter's soft eggs I discovered that the plastic eggs and this cement are NOT compatable and turned into a slimy mess.
Do not risk damaging your other flies or box with this cement
