sorry for the delay yo
anyway it would run you 360 to paint the chrome trim around the windows gunmetal and the grill trim black. as far as the headlights go i would have to see them because from the picture u got in your avatar i cant tell if the chrome trim is outside or inside the headlight.
the price is a little steep on that because there quite a few steps involved in making paint stick to chrome and that if only the item that is getting painted is plated chrome on top of plastic.
