Loon Outdoors UV Clear Fly Finish Flow – Ultra-Thin, Quick-Cure Resin (1/2 oz)

The Loon Outdoors UV Clear Fly Finish Flow is the thinnest UV-curing resin offered by Loon. Designed to perform as a head cement replacement or a delicate protective coating, Flow dries to a hard, crystal-clear finish while preserving the fly’s natural silhouette. With Flow, you gain control over layering and sculpting, thanks to a formula that stays remarkably thin while still delivering strength where it matters. This 1/2 oz bottle is compact enough for on-river tinkering and robust enough to stand up to repeated rework, giving you a versatile tool for precise, durable fly tying.

What Flow delivers

• Ultra-thin UV-curing resin that preserves fly profile and detail
• Infinite work time, enabling careful sculpting and layer-by-layer building
• Cures instantly when exposed to UV light, speeding up your workflow
• Cures hard and clear, suitable as a head cement replacement in many builds
• Includes a brush applicator for controlled, even coating

Real-world use and best practices

Flow is ideal for coating fly heads, bodies, and midges with a nearly invisible finish. The ultra-thin consistency lets you apply a precise layer without adding bulk, which helps keep delicate patterns true to form. When you have a brief moment of light exposure, Flow can transition from a workable state to a hard, clear coat in seconds, reducing the risk of smudging and uneven coverage. The resin’s clarity helps maintain the original color and texture of your fly, while offering a durable layer that can stand up to handling and light abrasion on the water.

Pair Flow with Loon’s UV Mega Light or UV Power Light for fast activation and consistent cures. The combination supports rapid iteration on patterns and color combinations, so you can experiment with confidence and return to a finished piece quickly if you want to revise details. The included brush makes precise application straightforward, even on small heads or crowded body segments.

How to use Flow

• Prepare your fly and clean the surface to remove oils or debris.
• Apply a thin, even layer using the brush applicator; avoid pooling.
• Expose to UV light (Loon Mega Light or Power Light) until the resin hardens and becomes clear.
• Repeat any additional thin coats as needed, curing between layers for strong, transparent protection.

With Flow, you have a flexible option that supports precise, refined finishes without sacrificing strength or clarity. The result is a finish that remains faithful to your fly’s original design while offering dependable durability on the water.
