Node texturing guide to starships.

I’ve seen some nive tuts on making metallic surfaces with nodes, and how to make flecked metallaci paint with various color elements to it, and that’s all bery impressive looking.

But how about making a texture like a starship hull with nodes? I’m trying with nodes and just getting metallic or matte finishes that are too damn relfective. Any tuts on making a nice star trek/star wars texure? Not evereyone wants a metallic texture for every object.
