@mhaze....just reflective shader and default shader with pfs as colour functions, though you can get results with just a surface layer/power fractal/or default shader and a reflective shader...just play with the colours especially the underlying colour and the reflection tint!...see attached clip file, just attach this to your parts shader!
@njeneb, thanks for the pointer, and thanks for the blender to tg tut, helped me loads!
