Lets talk about powder coating a fork and frame

What would happen if one tried to powdercoat an anodized part?

I'm thinking about getting a run down in white, frame, stem and bars.

However the stem and bars are currently black- would this need to be removed by Armortex/me before coating it, and would this be a simple case of Armortex grit-blasting the parts?

I've had an anodized motorbike muffler powdercoated and it came out well and cost fuck all. Was in New Zealand though so don't know what the going rate is here. I'm not sure but I think anodized colour is still bare metal so doesn't require any additional prep.
