Eastman03, there’s an art and a specific technique to using epoxy and it differs according to the brand. Envirotex Lite, aka ETEX, is quite different from Devcon Two Ton. ETEX is a pre-thinned bar top - decoupage epoxy while Devcon is a glue. As for applying heat, that also falls into the “art” category. Warming ETEX before brushing may be ok, though I personally don’t see a need for it. Heating an epoxied lure is also ok or maybe not. If you heat a freshly epoxied lure enough it will expand the air in the wood, forcing it out into the finish. So if you want to heat the lure, do it before epoxying. Also, a lure turner running in a box gently warmed by an incandescent bulb might work fine and shorten the cure time considerably. You can also use an alcohol burner passed quickly over fresh epoxy to draw out any bubbles (breathing on the epoxy can do the same). For me, heat is another variable and the fewer variables there are, the better I like it. The best technique I know of for epoxy, or any finish, or for any crankbait build step: have some patience. Haste makes waste. Measure and mix epoxy well and it will cure hard in its on time without further help.
