Fly Tying Varnish, Glue and UV Resin

Varnish, glue or UV resin: which to choose

Varnish, glue and UV resin are the fly tying materials that decide how long a fly lasts. They differ in how they dry and what they are used for:

• Varnish and glue – dry on their own. Varnish and shellac finish the head and are applied in thin coats, while superglue reinforces the fly: you coat the tying thread with it and fix materials to the hook shank.
• UV resin – cures only under a UV torch. Used for Perdigon and buzzer bodies, streamer heads and securing eyes.

Where to start

A clear fly tying varnish and a brush-on superglue are enough to begin with. They will finish most nymphs, wet flies and dry flies. UV resin and a UV torch become useful once you tie Perdigon nymphs and streamers with eyes, and on large spinning lures superglue works best.

What to keep on the tying bench

• a dubbing needle (bodkin) for applying small drops,
• a UV torch for curing resin,
• a stable bottle holder, so an open bottle cannot tip over.

Working safely with varnish, glue and resin

Work in a well-ventilated room and avoid contact with skin and eyes. Superglue bonds skin in seconds, and a UV torch should never be pointed at the eyes. Keep bottles tightly closed and out of the reach of children; the manufacturer's instructions are on the label.
