According to some customs channel on youtube they do. As for the details of technique I am not sure. I'm going to start on my Project: Ashe custom using an Other M Samus Figma next week. Have been swamped with doctor visits and work, so I've been making sure to order everything I could possibly need. I'll probably start on her drone first, then move up to her bow until I am 100% comfortable with the feel for the material since this is my third time scultping and first time making a custom toy.
