If you do use the Devcon, make sure it has some type of UV inhibitor, if you do not, your lures will turn colors after just a while on the deck. Also I have seen some heat the epoxy with a propane torch after applying it, this gets the air bubbles out, just a quick touch with the torch though, it will make a disaster of your job if not done correctly. I personally use a two part automotive clear coat, this can be applied by pouring it on, and letting the lure spin in a rotisserie, I currently spin over 80 lures at a time doing this, and when you finish the first clear, go back and clear once more and your done. I have lures all over the world and had only compliments on how much the clear holds up and how good things look after years of use. Not sure if this is for everyone, but that is my thoughts on that..
