Ok dude you need to go to autozone/advance auto parts and get Duplicolor "High Temp Engine paint" Get the gloss black, it comes out really nice. When painting, remove the lens and stuff and tape up the parts right behind the lens, then SPRAY AWAY lol. Go for about 4 to 5 coats. Then put it all back together and you are good to go. I chose to paint the whole entire housing gloss black instead of just some of the parts. Here is what mine look like:
Good Luck!
