Hi, Work progresses slowly on the Black Fly due to the spring re-fit progressing rapidly on the 'mothership'. As my 'Fly is going to see some rough usage on tidal beaches, I'm considering a tougher overcoat for the Dacron. I was wondering if anyone had tried covering the Dacron with Xynole as in this article: http://www.duckworksmagazine.com/07/howto/skin/index.htm Peter.
