Loon Outdoors UV Fly Finish

The thin version is designed for delicate, low-profile bodies where you need the resin to penetrate or coat evenly without adding bulk. The thick version is better suited for building up substantial heads, wing cases, or creating larger, more durable shapes.

Yes, you will need a UV light source to initiate the curing process. While most standard UV fly-tying lights will work, ensure your light is functioning properly, as the resin will remain tacky indefinitely until it is exposed to the correct UV wavelength.

When cured properly with a strong UV light, this resin dries to a hard, tack-free, and glossy finish. If you find it remains slightly tacky, it usually indicates that the light source was too weak or the exposure time was insufficient.

Absolutely. Because it cures instantly under UV light, it is an excellent tool for quick field repairs on damaged heads or bodies, allowing you to get back to fishing immediately.

One of the primary benefits of this product is that it offers infinite work time. You can shape, smooth, and adjust your fly as much as you need without the resin setting until you decide to expose it to the UV light.
