The hundreds of flies can be treated is a very accurate statement. Already treated around 30 flies and have not put a dent in it. They also float significantly better after treating them.
I can treat the flies (I think will work?) I'll be using the next and be sure they'll float like top.
I treat every one of my dry flies with when I 'm tying. Floats the fly forever! Also works well on treating the tips of older floating lines. Love it, just love it.
