If it were me, I'd have the camera painted, then sent back to you. Then send it out to DAG or whoever else for the CLA.
BTW, those folks in London told me it was about an 8-12 week turnaround time for a repaint. Its also very expensive. I think theres enough resources on the net to do it yourself. If you have the right tools and take your time, it should be no problem disassembling the camera, take it to a local chrome plating shop and have the chrome stripped off, then spray it yourself. Afterwards, send the disassembled camera to your repairman of choice (taking care to make sure all parts and pieces are neatly organized, etc). Then all thats left is repair and reassembly!
