Give meguiar's ultimate black a shot on the exterior trim. You can pick it up at your local auto parts store. You also want to make sure the trim is clean so it adhere's to the trim and not run. Also apply it thin.
You can get them on ebay or amazon. Do a search for grand prix LED. The red one's look the best in my opinion.
As redcompg stated they are only painted when doing a retro with projectors. You don't want to paint them with halogens unless you don't want to see at night. Stick with factory lights unless you plan to retro projectors. With stock lights look into HIR headlights. They are still halogen type bulbs but with better light output.
