i did mine and used dupli color high temp black black paint. its the same i used for my headlights and emblems also. i sanded down the cut out with sand paper, starting with lower grit number and working my way to a finer one. i cant remember the exact grit, sorry. but i then taped off the area i didnt want painted and used an exacto knife for a clean, precise cut. it helps to shake the hell outta the spray paint and then let it sit in HOT water. that helps the paint atomize for a more uniform coat. did very light coats with about an hour in between coats. i wasnt in a rush and it took me about 1 hour prep time and 10 hours of painting and drying. let me know if you have any other questions...
