This is the Tamiya kit built box stock, painted with Tamiya TS8 and unpolished because the real F40's have a rough finish due to the kevlar weave pattern underneath the paint.
I used a .005 black pen to color in the 'belt'.
This is a joint build between my nephew and I, he started the kit years ago as I was teaching him how to build, then he moved away and no longer had time to finish it. He had assembled the chassis/engine and most of the interior, I painted the body and finished it.
