What kind of gun are you using for your painting?
I bought a couple air brushes to do mine but you have to thin the paint so much that I have trouble getting it to stick to the plastic. Not only that, but changing colors was a hassle with only two brushes. I found it was best to do a big run of one color at the same time instead of trying to do one lure one color, and then paint another one a diff color.
That is..until I got the mini spray gun. I saw one at the automotive paint store and bought it. It only holds about a half pint and can actually spray a pretty narrow bead for smaller objects. But I can mix paint thicker and use better paint too that just wont go through an air brush nozzle. Not only that but I can swap colors real fast; just run some acetone or something through it to flush out the old paint color and put in the new. This works a ton better for doing the base colors and main colors. When I wanna get creative with stripes, gills, or eyes, I will just use a simple paint marker and then shoot a coat or two of clear coat over top of it all and let it dry.
I am trying to get the bluegill pattern nailed down but there is a lot of different colors and things going on with that pattern that I ain't exactly figured out yet.
