Nice one rob, here let me show you a tutorial that is really good for hard surface textures. http://www.3dtotal.com/team/Tutorials/stefan_morrell/stefan_01.asp
Art Institute of Pittsburgh. So does Virtuosic for that matter. We high-five each other regularly. I'll probably be saving that tutorial for next quarter when I actually have time to make the good stuff look better than good I hope. :/
