I purchased three seated/squatting/kneeling GIs or sailors. Two could be sailors because they have gray helmets. One is kneeling and eating with one hand and holding a cup in the other. One is kneeling with a blanket on his lap and the third one is seated and washing something in a bucket. The question I have is whether I would be foolish to paint them with more accurate colors. They do not have a matte finish. I would appreciate your advice.
