um...I just collected the D3 from Nikon just now, didn't get it fixed, I can't wait. I have to shoot it like a film SLR.
But there is something really interesting after I got back the cam. I have noticed some rubber didn't sink very well into the camera body, i force to lift the rubber, noticing there are some screws underneath it. I guess Nikon has to lift up the rubber in order to examine / change the PCB, but it's glued with something like double side tape
As for the peeling paint, I don't think it's the kind of peeling you guys talking about. The peeling just leaves a smooth black colour surface(original nikon paint has a slightly rougher surface), not the metallic silvery colour.
I will be in HK next month, I will try to fix the D3 there if possible and let you guys know how much it will cost
