I don't know if this has been mentioned here or, not but Krylon has a wonderful new product called Plastic Primer. Originally intended for use on outdoor furniture and other outdoor plastic, it works with outstanding results on plastic Armymen. After doing the usual soap & water wash on the figures, give them a light coat of Plastic Primer and then paint them, as you would any metal or resin figure. The dreaded flaking off of paint will cease to be the problem that it has been in the past. FYI.
