Here's a pic of Zippy's (Rob McPhee) dash that I painted.

I just used a 3M red scotch brite pad with soapy water to stip off the soft grey paint (it takes an hour or so but won't damage the plastic).
I then sprayed it with plastic primer, then epoxy primer, lightly sanded it, then painted it.
The black is Organsol black (textured black) and the red is Viper red.
I posted a detailed description in january of this year.
Personally I've seen solid red painted dashes and I didn't care for it too much. A little too obnoxious for me (and I like obnoxious). Another problem is that the plastic isn't perfectly flat and smooth (molding depressions and lines) which shows through unless you fill and smooth them out (That's why they use textured paint from the factory).
