your going to have to troll the net for a face cover material. (sky's the limit really) if your talking about something to cover the metal and then put the gauges in, for a finished look. you could even cover it with leather if you wanted to, ( or that carbon fiber stuff) the way to stick anything to it is with rubber cement in a spray can, you spray both sides of what you want to mate let it dry, press it together, real easy.
