It was pretty tought to get a similar render result as Kent did. Despite the fact I was using the same values as he did for all nodes. So I was playing a bit arround with all colours, color ramp nodes and so on. Mainly I had to set the saturation of glossy colors much lower and go a bit more to the yellow hue. Now I think my metal base shader is not bad.
Maybe it was all caused just by the color difference between my blender render and video render of the tutorial itself. :-)
But really dont know why is there so many black spots on my dial circle on the lower half. Any idea? :-) Thx... Might be caused by the dirty vertices.
I've learned a lot. Thank you very much, Kent!
