I once used jig head enamel paint somewhat thinned out with, of course, paint thinner. Worked pretty darn good. You have to be careful with your decoy so as to not crumple it up otherwise it will crack and chip. I only used it on the head and for the body I use normal old spray paint and then touch up with white on the feathers. A horned up ol' tom won't pay much attention to detail other than it's brown and available.
