Smoothes and strengthens knots right away.  Lightly coat newly tied nail knots and they'll shoot through your guides.

With UV Knot Sense you can smooth and strengthen your newly tied knots immediately. After application, it dries instantly with Loon’s UV Mini Lamp, UV Power Light or with direct sunlight. Also works great for repairing damaged flies and completing household projects.


  • Ideal for coating knots for strength
  • Smoothes knots to easily slide through guides
  • Cures soft and pliable
  • Instantly cures with sunlight or UV light
  • Quickly repairs damaged flies

Directions for use:
While shaded from the sun, apply enough UV Knot Sense to coat knots. Rotate line or use applicator to form UV Knot Sense to desired shape. Expose to sun light or use one of Loon’s UV lights to cure. In direct sun (or when using Loon’s UV Lights) hardening should take approximately 15 seconds.

Wish that I knew about Knot Sense years ago. Works great, cures in the sun or any other UV light source. Fly Line/Leader junction never hang up on the Tip Top anymore. Nice!
