Quick take

A clear UV-curing resin that instantly hardens knots and fly-tying wraps with UV light or sunlight.

Loon UV Knot Sense is a low-viscosity liquid resin that you brush over a freshly tied knot to smooth it so it slides through rod guides. It stays soft and pliable once cured, and sets in about 15 seconds under sunlight or a UV light. Fly anglers also use it to patch up a damaged fly, and it suits connection knots like the FG or uni-to-uni.

Best for

  • Strengthening thread knots on fly heads
  • Sealing and smoothing thread wraps
  • Repairing damaged flies in the field

Skip if

  • You tie traditionally with thread wraps only
  • You do not have access to UV light or sunlight

Strengths

  • Cures in 15 seconds with UV light for fast workflow
  • Smoothes knots for easier guide passage
  • Clear finish is nearly invisible on finished flies

Trade-offs

  • Requires UV light source or sun for curing
  • Slightly increases fly head weight and profile
  • Can be applied unevenly if not careful with brush application
