I have been using Loon resins for awhile and find them consistent. I especially like that Loon products commitment to clean water.
I have used most of the products Loon makes for UV over the last few years and I love them. Consistent quality, last long and holds up to getting beat around on rocks.
I first tried the "Thick" UV Clear Fly Finish which immediately elevated my scuds, shrimp, and eyes on bigger flies. I liked it so much I picked up some "Thin" later that week to use for head cement and to immediately keep things in place while I'm working on flies. These products (along with my UV Bench Light) have elevated my fly tying more than any other product I've tried. I'm hooked!
Buy it and try it- you won't regret it.
I use the Loon UV for tiny drops or large applications for body development. Using the tiny drop has eliminated using a whip finish.
