The interior was airbrushed with a custom mix of Tamiya X-18 Semigloss Black and XF-2 Flat White in a ratio of 10:1 or ten drops of black for every one drop of white.
The trunk was flocked with Detail Master Black Flocking. I added some silver accents with Tamiya Chrome Silver. I didn't flock the floor because you won't see it on the finished model.
The pedals were painted with Tamiya Titanium Silver.
The seats also have a custom color. I used Tamiya X-6 Orange and XF-3 Flat Yellow in a ratio of 1:1.
The seat back was sprayed with my custom interior mix that I used for the interior tub.
