MAC is a very special shade of red. It has just a hint of orange in it. Don't try to match it with something off the shelf. Get a custom spray can mixed up. If you have a drawer that still has some nice paint on it, you can take that drawer in to have it matched. If you have a MAC socket tray, you can use that. If you have a local store that specializes in automotive paint and body shop supplies, call them up on the phone and ask them what they can do for you. If you're going to use a spray gun, have them mix up a quart at the correct viscosity for spraying through a spray gun.
