Bartamos, yes, the dark brown, pretty much the color of chocolate is the original dash color, which is also inside the glove compartment and also under the build sticker.
Mike: I have used an Omni single stage on the firewall, and was real happy with the outcome. As I mentioned in the previous post, I have read on the paint sheet that the dash paint was 10% gloss. I don't know if this can be done with Omni paint, but if so, that is what I would assume I would use.
