interior paint

It comes down to flattening additive. The interior maroon has 2 main shades- gloss (for doors and most of the interior trim) and flat (for dash, interior window trim, and cargo sides). Both use the same formula (which is really the same Maroon as the exterior code). Just experiment with the flatting additive. For a fastback, there is a third color- the rear trim is slightly darker than the door trim, but you wouldn't know the difference once painted unless someone is doing a point car. I did all the my interior gloss with the maroon, then asked my paint store to mix me up a smaller amount and add flatting additive for the steering column, dash, and side windshield trim. A mix-up of a semi-gloss can be used on the the plastic kick panels to make them look more "plastic" but that is up to you. Take a look at my before and after. Not much difference!
