Here in salt lake there is a large industrial paint vendor. I can get the name from my buddy tomorrow, but the point is, you go to any large paint vender and tell them you want to paint on rubber, or hypalon. These are still extensively used on roofs, etc. They will have colors. These local guys will even put it in a spray can for you. I imagine Boise has a similar business. I have been unable to find gacoflex anywhere. Demaree inflatable Boats sells paint, but with the hazard shipping and all it gets to be $50/qt.
