Loon - UV KNOT SENSE - Head Cement - Quicker & Easier than Epoxy
Thick like Honey, but clear as Gin. Fast and Easy to use.
Put a drop of this on the head of your fly, then flash it with a UV light until firm.
Direct Sunlight works too. (Not through windows or glass)
Dries hard and clear.
Carry some with you on the water to repair flies, or use it to coat knots in your leader for a smooth finish.
