UV Treatment Spray for Flies & Tying Materials

Turn your favorite flies and fly tying materials into UV-responsive creations with a simple spray.

Until now, adding UV response to flies typically meant using specially manufactured UV fly tying materials. Hemingway's UV Treatment Spray changes that.

This innovative, eco-friendly, water-based treatment allows you to enhance the UV response of existing natural and synthetic fly tying materials, as well as finished artificial flies.

Whether you're tying new patterns or upgrading flies already in your fly box, you can add UV response without replacing your favorite materials.

Add UV Response to Almost Any Fly Tying Material

Use Hemingway's UV Treatment Spray on a wide range of fly tying materials, including:

  • Natural and synthetic dubbing
  • Feathers, hackles, and CDC
  • Synthetic fibers and wing materials
  • Hair, fur, and other natural materials
  • Finished dry flies, nymphs, wet flies, and streamers

The treatment is virtually invisible in daylight but produces an enhanced response under UV light.

Unlike coatings that can stiffen materials or alter their movement, Hemingway's UV Treatment Spray is designed to preserve the natural flexibility and movement of treated fibers.

Perfect for Fly Tyers and Fly Fishermen

For fly tyers: Add another visual dimension to your existing materials, experiment with UV effects, and create new variations of your favorite fly patterns.

For fly fishermen: Simply treat selected flies from your fly box to give them an additional UV response.

How to Use

  • Spray a small amount onto the material or finished fly.
  • Spread lightly for even distribution.
  • Allow the treatment to dry completely.
  • Use a UV light to reveal the enhanced response.

Why Choose Hemingway's UV Treatment Spray?

  • Versatile application: Suitable for natural and synthetic fly tying materials and finished flies.
  • UV-responsive finish: Virtually invisible in daylight, with an enhanced response under UV light.
