I got a pre-shaped popper from jannsnecraft and the lip of it is not concave, its flat, just at an angle. How would i go about creating the concave lip to make the popping sound?

So im thinking about buying a wooden popper from jannsnetcraft.com And a block of basswood for making my first cranks. I'm a complete noob when it comes to custom lure making so bear with me haha. How do i seal the lures before painting? Another guy told me rub super glue on it with my fingers, but i have used super glue and touched it with my finger and it pulled some skin off, unless he is talking about some other glue? I was gonna use stainless steel wire for the hangers and line tie but, what gauge wire should i use to make them? 20? 21? Split ring for a crankbait? I was thinking size 3? Once sealed, do i need to put primer on it or can i just paint? I dont have an airbrush but i was looking at buy some spray paint. Anybody got some pictures of lures done with spray paint? I don't have enough money to buy and airbrush and a compressor. Much appreciated!

I bought 2 things of devcon two ton epoxy and some coiled 19 gauge steel wire for my swimbait. But the wire i got was really bendy and it was the only 19 gauge wire i could find, it was also annealed. I think ima return that and get some regular 18 gauge wire. Also when im done shaping my lure, should i paint it first and then epoxy or something else?
