Cutthroat Leaders "Otter Butter Floatant

I originally bought this product to float a furled leader. I was using red tin in the past and only got 2-3 hrs float time. With Otter butter I get a day + so I don't have to fool with floateant during a trip. Keeps the leader floating high for dry flies. A complete bonus cam when I descovered it is a great floatant for new fly lines as well. I have tow lines which the tip would start sinking after an hour or two. After cleaning I applied to the lines and they now float like new.
