This P-51D cockpit is entirely out of the box except yellow cushion on the seat made of TAMIYA EPOXY PUTTY and PE instrument panel. The floor on the real Mustangs was made of wood and painted with black anti-slip colour. This colour became usually very soon heavily worn up. To simulate this effect I used AMMO Scratches Effect (this is the weaker one from the two different agents available from AMMO) and a cheap very stiff brush with trimmed tip.

Step 1: two different tones of brown colour (AK RC) were sprayed as the basic cover to simulate wood layer

Step 2: Two thin coats of the chipping fluid was sprayed

Step 3: Thin layer of TAMIYA NATO Black diluted with X-20A thinner was unevenly sprayed (with even more thin layer over the place I intended to scratch later)

Step 4: With the help of the water and the stiff brush I very carefully and with a light hand made scratches in the forward/backward direction (the same as the pilot’s feet were moving while steering the plane with the rudder pedals).
