Steve_Sullivan I still use that liquid Dry Fly Silicone Mucilin. Clear bottle green label, manufactured by Thames Fishing Tackle, Redditch England. I buy all the bottles on the shelf whenever I find it. Still have about 3 bottles from a batch I found at White Elephant in Spokane, Washington. I love the stuff even if it does leave a little greasespot on my special floatant pocket of my vest.
