This has been available over at Ashundar for a while but as the subject of chrome has cropped up again I thought I had better add it here as well.
Two images:
The first uses sharp reflections, the second uses slightly softened reflections which give a more natural result in the areas where the object self reflects.
The clip file creates the second result, two nodes as the highlights are a combination fudge of tight reflection from the reflective shader and slightly softer specular reflection from the default shader.
BE WARNED!!!
The render time overhead is nasty. Sharp version 9 minutes, soft version 43 hours 24 minutes. Complex test object with lots of self reflection; simpler objects should do better
