UV-curing resins with multiple functions, all while curing in seconds.
UV resins allow for infinite work time but cure within seconds when exposed to one of Loon's UV lights. The result: a perfect application with a durable, clean, and glossy finish.
The three different viscosities were developed to perform in three different circumstances:
UV Thin is viscous enough to build heads or wing cases, but thin enough to coat bodies on small, low-profile flies. Brush included.

Also available
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 Thick is perfect for building big heads, bodies, and wing cases.
