Re: Custom painting lures?
I don't paint plugs but for spinners I use the cheapest neon colored nail polish I can find. It sticks to anything and dries quickly. I usually paint them up on the boat when I'm plunking since the brush is built in.
No, you can't get an airbrush transition between two colors but in my experience the fish really don't care.
The colors I keep in the tackle box are neon green, neon blue, bright pink and a clear one with glitter. I can make up spinners, paint them, and be fishing them 15 min later.
