The UV resins work, but are really expensive as Poop states above. I use the UV stuff only for things like the wing case of trout flies and smaller jobs. I may use UV to do one or two flies, but I usually at one time tie up a bunch of poppers or saltwater or muskie flies I use the same epoxy I use to coat threads for rod building since I already have it on hand and have no need to buy anything else. I paint and tie a bunch of flies or poppers and mix up a batch of epoxy. It's perfect for poppers because it protects the paint and remains flexible and clear. I attach a foam disk on my drying motor used for rod building and coat and hang each popper on the foam to keep them rotating until dry.
I usually do a whole bunch of poppers each winter for the upcoming smallie season in summer through fall. No need to do any this winter, though since the monsoons kept me off the rivers and streams last year and I still have a ton of unused poppers for this coming smallie season. Like everyone else, I'm hoping for a better season this year. Good luck to all.
