Forgot to add.  That when working with metal material, in order to get the reflective quality don't forget to use "RayTracing" in the Firefly render settings. Set it to 4 bounces.  You also need to have something in the scene along with the metal object to reflect off of.  A sky dome is a great thing, or some props strategically placed off screen.

RDNA has a free sky dome in their free stuff area. 

I don't like to use the dome as a background, so I tend to tilt it up using the X Axis parameter dial until it vanishes from scene window.  I still get the benefits of the sky dome, but it's not being rendered as part of my scene.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
