Jim, that must have been Kelley because I have not painted my antenna yet.
Mint, I have a Ceramic White LS, and the black satellite antenna sticks out. See photo. I contacted the guys at thesiriusstore.com, who used to paint antennas under the name colormatchantenna.com, but no longer do this. They recommended going to a body shop to have it painted, and that's probably what I'll do.
As a cheaper alternative, you may want to get some paint from Paintscratch.com. They sell it in spray cans, but be sure to get the flex additive that is suitable for plastics. One point to consider is whether the paint will affect radio reception -- I've heard that some metallized paints do, but I'm unsure about the stuff from Paintscratch. You should ask them about this.
