Hunt's Original Floatant is a soft powder that will keep CDC flies afloat for longer by providing a protective barrier that works in even the toughest of conditions. To revive flies, simply work the powder into the body and wings of your fly with the easy to use applicator brush provided. Remove any excess floatant with a few false casts and you are ready to go. It can also be used to coat nymphs, that once underwater, will produce air bubbles that can look like the realistic effect of an emerging insect.
