I have two,
Adding epoxy to sharp a edge that the epoxy will not stay on. On my bigger musky baits I put three layers of epoxy. Put on the first coat then before adding the second heat up your epoxy so it dries faster and let set until it is almost too stiff to put on then add it to just the sharp edge. Let it dry and sand before adding the next two layers of epoxy. You may need to repeat after the second and before your final coat of epoxy.
Make sure you wood filler is dry before you paint and clear your baits. This is one way you can waste time fixing crack and peeling baits.
