I have been using UV Clear Epoxy for a while now and appears to be pretty good. I have had a 2 inch "puck" on a piece of tape stuck to the side of the shed (in full sun and frost) and have been checking for colour change and brittleness for about 2 years, hasn't changed at all, still quite clear and still bends without cracking.
What I like is you can paint it on, warm it up and rotate it (if you want), cure it for 15 sec with a UV light/torch and its all over--give it a bit of sunlight for the final cure---no more gunked up brushes, OR doing 6 at a time, and waiting 12 hours before you can touch it AND it makes my colours POP---(make sure you use an exhaust fan if indoors).
I've been making lures (trying to) since 1979 and this stuff has given me a new lease on life, there's an extra day in every week-----It's a bit like getting a dishwasher or washing machine Just ask your wife. Pete
