Glow in the Dark Floatant

Floatant is the stuff you rub on dry flies to help them stay dry as you whip them against a river surface over and over.  The stuff I use is a type of gel you rub on the fly.  In Idaho there are a few times a year when the fish go crazy for a bug that hatches or is active close to sun down.  There needs to be a glow in the dark floatant you could rub on for those few times a year where you want to fish in the dark.
