I believe one could get good results from a little sanding and then an application or three of Krylon Fusion paint. It's formulated specificaly for adhesion to plastics, and the finish and application process is very user friendly. I used it on the bottom inside of my Memphis shield without sanding first in order to block out some annoying headlight and driving light reflections. 8,000 miles later, no chips or adhesion issues.
A little OT, and perhaps not applicable to console painting - I've used Hammerite brand rattle cans on bare metal. I just wanted to share that the stuff works as promised, and the results come out looking like a hammered / rippled finish. Cool stuff.
