I've used Rhino and I recall it has a material(shader) property called Clear finish. It is quite like the fresnel effect and is used for making the surface more reflective as it turns from the viewer and look like lacquered. So I think you quite definately need the Shader Ops and its fake fresnel to create similar materials. Once you-ve got it add the fake fresnel into the reflection slot Just as Ewinemiller has it. In Rhino the material blends into full colorless reflection as the material turns away. I have no idea what the value for the fake fresnel should be but maybe Rhino can answer that if you check the carpaint-shader. There might something else to Rhino's materials but I cannot remember them right now. And probably you need something more to reflect as Hoofdcommissaris said. I wish I could test this first myself but I haven't been able to get the shaderops demo working (what does that tell about my suggestions)...
