The thing with the metallic surface is to get a good HDR environment so the reflection becomes more realistic. Like a hemispherical environment but not render it only the reflection.

Exactly, I only found one suitable one, for the other environments the reflections where either too strong or two week. This was better

The best solution in this kind of render is to get an indoor environment and to blur it, then exclude it from render and keep the reflection.

Awesome - thanks for the advice I will try it in the future
