Realistic Metal (paint and chipped paint) in Mental Ray(Mix8?)

I'm trying to find a way to do this as realistically as possible in Maya. I want my robot to be painted and the edges to be chipped, and worn to reveal a brushed steel type look. And in some places simply chipped...

I have a very detailed robot so I would like to do this somewhat procedurally. I want to be able to simply paint a black and white map to reveal the underlying brushed steel surface.

There doesn't seem to be a layered shader in maya so can I use the Mix8? How would I go about doing this? What would I plug my black and white map into?

Hoping someone who has experience with this could help me out, thanks...

first off, there IS a layered shader. if you go to the hypergraph (window-->rendering editors-->hypershade) on the left (under create maya nodes) you can create a layered shader right off the bat. secondly, you need to UV map your creation. the easiest way to do this is with 'polygon UVs'-->automatic mapping'... although depending on the complexity of your model you might want to look into other combined methods... i leave the rest to you.

Accept no substitutions.

People have told me that the layered shader doesn't work properly with Mental Ray and that instead I should use the Mix8 Mental Ray shader by francesca.

Could someone tell me if that is true... or maybe the strengths of each methods, why one might be better than the other.
