I do a fair amount of jig pouring / painting. Initially, I dipped the jig heads in vinyl paint, but soon discovered that they are not durable. An hour of fishing in rocks and the jig is toast. It'll still catch fish, but it's no longer pretty. I now powder coat all of my jig heads and then bake them to get that lasting finish. I've owned an airbrush for several years, but it's still in the unopened original box. Maybe one of these days....
About the only time I use vinyl paint anymore is when I get a wild hair and paint frog designs on the backs of Crockers or "Big Foot" Toads. (Dip them after painting.)
