I used this for making small wing cases on my flies. It goes on very thin and doesn’t run. Cured in 15 seconds under direct sun. The finish is clear and strong. Perfect for delicate parts.

Great for small thread heads. It’s easier to apply than the regular version. I didn’t have to use a lot, and it held up well after curing.

Used it to make a small head on a dry fly. Applied thin, cured quickly, and the result was smooth and durable. Works well with my vise and UV lamp.
