What the OP can do is try to find somebody doing Electrostatic Painting, that paint is not baked. My old miyata pro had that finish, the nice about it is that is not baked, second the finish gets almost as hard as appliances finishes and pretty much you can paint over chrome plating, sure you guys have seen several japanese frames that are chromed under it, that this has to be Electrostatic Painting.
The other advantage is that the layer of paint is quite thin as regular wet paint, so any frame embedded in the frame or fork will be nicely kept.
For the record never seen anybody doing this for bikes so could be a challenge to find a guy doing it.
