From this forum I believe that the engine bay to be correct would be a flat black. My painter is trying to get me to go to a satan. He says that the flat color will look dirty, smear when you rub it and overall let me down after a short wile. He is suggesting to go to a satan. Says it will clean easier, wont look like it is smeared and probably show better. I am trying to be as correct as I can in finishing this car. What are the opinions and suggestions here? Thanks.
