I have played and am playing with this a lot. If you are going to rattle can it, Duplicolor flat black ends up looking exceptionally nice. Only the dash and steering column though. The rest of my interior, while originally black was not the same type of paint or finish. You can pay a lot to get the absolute correct finish or a little and get something that is looks real nice. Also, I have tried clearing over satin, flat, and semi-gloss with really bad results. Nobody makes a clear flat in a can that I can find. Clearing(satin) over flat did some real strange stuff producing a hazing affect. It is your car. spend your $$ where you want but for me, the flat black rattle can actually came out looking nicer that the dash did from the factory.
