" ...boolean but the thing is, i'm not a NURBS yoda and..."
Don't worry Yoda doesn't know how to work with NURBS either, I have heard he is quite good with a lightsaber though.
but that could be an unconfirmed rumour of some tabloid no doubt :p .
I would do what Gect suggested
, metal is mostly shading and for textures you could use procedural 3d textures, in case your uv's are screwed up.
