Thanks. I think the finish is probably not too far off that. I've got some pictures up at

I am in scotland and currently use an anodisers in Glasgow. They however don't have too many examples of various colours. Do you have any associated anodisers in the UK or could you recommend anyone?
I suppose I'm looking for a transparent coating - almost like when you draw on polished aluminium with a felt tip pen. I suspect if such a thing exists the finish may be less durable ? Or am I underestimating the variables in anodising?
