Oil. A hunter who had a saw asked me to paint one of his trophies on the saw. I’ve done them before and it’s always handled with care. I use gloves to move the saw when I have to. The surface of the saw always has to be prepped before paint is applied. When the paint is dry and ready for display, position it and leave it where it can’t be handled as the surface may be dry but one scratch can destroy it. I had prints made for this one and titled it “Muley Season”.
