I like No Snow. I applied it 2 or 3 times before my trip to Alaska. To test, I stuck the fletched end in my pool and swished it back and forth pretty hard a couple of times, pulled it out and gave it a flick - it was bone dry. Don't know how it would have held up in sustained rain, as we had great weather. The other thing I liked about it was that it did not soften my fletching to any great extent. I've tried the paint on dry fly dressing that comes in the little "fingernail polish" bottle and the white powder, both are a pain to apply, and didn't work that well.
