The dashboard was initially primed while not separated from the bundle and I painted it there as well. The attachment point is on a non visible line of the part, so that was easier to handle that way. I painted it semi-gloss black, with three layers, changing the brush direction for each of them. If I did not paint first lengthwise, then crosswise, the brush pattern is too visible and not a nice thing. Both sides were painted with the same method. 
Once it was dry, I painted the dial rims and start/ignition panel in chrome silver. Some black touch-up was needed afterwards, of course. It is worth doing it neatly in order to avoid the "hand painted in China" effect that ruins everything. The inside of the dials is also chrome silver.
