can't rust it doesn't soften that's the basic plan for a car that can last for a century if that's what you want. to. go doesn't have metal panels that all made of thermoplastic and i'm ready to mount so the eco plants doesn't need painting facility. if you can produce a painted surface like this and it's also extremely durable it takes four times the normal force to scratch it and then you can hardly see to scratch and because the material itself is colored there is no problem a coating that makes it a wonderful material. but the path from concept to serious production from scientists to car maker was anything but wonderful. i think during the nearly four years since we set up the go mobile there have been six or seven disasters where we could easily have given up. just said ok that's that.
