First I cleaned the snot out of it, degreaser, and since I was not sticking to stock colors, lacquer thinner to stubborn spots. Blew it dry and then looked for scratches I could sand smooth. I did not need any filler, there were no deep scratches.
Paints were rust o leum paints for plastic. Just taped off and took my time. I can't tell you how many hours I have in it.
Thanks bud, I might tackle this project thus winter for my demon. I pulled my grill off my Dart an painted all gloss black back in high school so it's time for a change I think back to stock
