i allways apply floatant to my flies right after i tie them... i let them dry fer 24hrs before using them.... i tie lots of flies so i dont have to wory about waiting for the batch i just tied to get dry before i can go fishin... i really like the (water shed) floatant best... it is a permanant FLY floatant... capitalizes fly because its just for flies... put this stuff on a silk fly line, ya gona ruin it...
