Painting a car flat black?

Ive done so many of my beaters with rattle can out in my driveway i could do it with my eyes closed, even a noob can spray a flat or semigloss and have it come out lookin sweet. just do a section at a time using light coats. and the scothcbrite pad method is the one ived used every time. works sweet, just stay away from powerwashers for awhile.
