I'm working on a rifle prop for my Mami Tomoe costume, and I'm wondering if it will be okay to carry if I paint the tip orange? It's made of wood, paper mache and craft foam, and none of the pieces are movable. (Currently it looks like this http://i.imgur.com/WpInXV2.jpg, and will be painted white and brown to look like one of her rifles here http://news.toyark.com/wp-content/uploads/sites/4/2011/09/Mami-Tomoe-4_1315680054.jpg)
