Gulff Duck Floatant can be applied to any dry fly for superb floatation. Especially some popular dry flies, like the Klinkhamer, more or less require the use of floatant to work properly. You’ll also considerably improve the effectiveness and use time of other dry flies with it – especially if you are expecting them to repeatedly get manhandled by aggressive takes. Also available: Gulff Duck CDC Floatant especially for CDC dry flies.
