Haven't painted yet, I got some brake cleaner on it by accident so I know that part works. I'll probably use something less caustic and hazerdous when I do it for real.
I picked up some cans of krylon fusion for plastic paint in hammered metal silver and black. I can't decide, the cap samples both look really good in the Trac. I want the silver for the factory look, but the black is like a nice dark graphite that I think would look awesome.
Others here have used plastic primer / adhesion promoter and then painted the bezel / console / handles to match the exterior paint, or just about any color you could imagine. There are some really nice examples on this site.
