Loon Lochsa Floatant. 1/2 Oz Bottle. Quite possibly one of the best floatants on the planet. It's a gel-based floatant that even works on CDC. And like Aquel, it's silcone based and isn't affected by the heat or cold.
Loon Aquel Floatant. 1/2 Oz Bottle. This is some of the best gel style floatant you'll find. It doesn't melt with heat or get thick in the cold and won't leave an oil slick on the water. Just FYI, it's pronounced "ahh - kwel"
