What paint is safest/best for repainting a plastic grill?

[slam59]

I have read where some have used Duplicolor FM149 which I think is Argent silver, on their plastic grills. Was wondering which is safest to use on the plastic, cause I just picked up a perfect 74 grill for my truck and it is so very straight with no defects just needs repainting and I dont want to use a paint that will mess up the plastic. Dont know if engine paints are good for plastics. Also, is thr Dupli color Argent Silver a Chevy/Gm or other? I thought I seen where it was like a Chrysler color or other, not Chevy, but I have read where guys say thats its the color they use on their Rallys and grills. Thanks..
