We use Loon Payette Paste during the hand crafting of our leaders. We have used / tested many different brands, as long as you use a paste type floatant, you should be good. Gel floatants do not adhere to the thread as well as paste type floatants. We use / sell so much of the Payette Paste, that Loon has allowed us to “co-brand” sell the paste under our own packaging. Remember, to save $$$ on our site, use the coupon code NAFFF.
