The biggest problem with painting plastic figures is that the paint tends to flake or chip off, especially around flexible parts like rifles and swords. The best way to avoid this is to coat the entire figure in liquid latex (which is typically used to make molds). A very thin coat of latex acts like a flexible glove around the figure. The paint will bond or adhere to the latex and remain flexible even when stressed. Latex remains tacky even after it has dried so avoid handling the figure as much as possible and watch out for pet hairs!
