Loon UV Clear Fly Finish
Use these UV curing resins to build fly heads and bodies. They come with a brush applicator and UV blocking application needles. The taper-tip prevents clogs. Cures "instantly" when exposed to sunlight or UV light. (Using a Loon UV light, hardening should take about 15 seconds.)
UV Flow is the same viscosity as water and locks in threads as a head cement and provides a super-thin coating to heads, bodies or midges.
UV Thin is viscous enough to build heads or wing cases, but thin enough to coat bodies on small, low-profile flies.
UV Thick is perfect for building big heads, bodies, and wing cases. This is what Brett uses for Copper Johns.
