2013-05-10 10:21:43


After two years of research, a high-performance paint that can be applied by roller is chosen for the “Gracehoper” project. The paint is durable, easy to apply, and commercially available should there be need for “touch-ups” in the future. A large tent is to be installed over the structure to maintain the ideal environment for painting.
