Wow , I have lost more than 2 lures to a bad coat ( my fault ) epoxy can be temper mental ( just about any top coat )
1. measure and mix properly
2. few drops of denatured alcohol to thin, mixed
3. use a decent brush ( better brush helps me )
4. learning curve hurts sometimes, just learn from your mistakes.
D2T is pretty forgiving if you got everything lined up and ready to go, you might want to find some older/trash lures to practice on so the learning curve does not hurt so much.
be meticulous.
IMO.
