if the car is a factory color, you can go to www.towerpaint.com
and get it in a spray can. comes out looking very good if you prep the grill first properly, and take your time and paint it right. Is that worth several hours of your time? If so, worst case is you restrip it and you are only out lets say $50.00 for materials and X hours of time. But for $125 I would just have it done, or try to find a place to powder coat it as stated.
