Need to coat these billet grills, they are satin black with polished faces , she wants them all satin black. I will find out if they are clear coated or not. If not I should be able to go right over the polished with more sating after blasting the faces. If they are clear coated do I need to do anything besides just shoot satin over it? Price for doing these 3 2001 Mustang grills ?
