Well for sure move to a high quality slow cure epoxy. Joe Peterson's Tru Coat, Envirotex, Alumilite Clear cast, Devcon 2 ton (slow cure), BSI 30 min, there are a bunch of them. All of them can provide much higher quality results! And for the most part, I would do 2 or three thin coats, depending on the epoxy I suppose, and depending on the potential use of the lure. Making large wooden muskie lures, I like 2 or three thin epoxy coats. And I love the look of epoxy when it is done well!
