I'm really entering new territory in trying to get the rat-look to this car. The rust is ok right now, but it needs to have a matt finish. Its too glossy right now. Another thing I notice when I look at these pictures is how boring the car body is. The central point of the model is the roof of the car and there is nothing there to look at. To solve this, I plan on adding a rider to the roof, who will be magnetized in so he can be removed during game play.
Other stuff on my workbench includes some sort of Nux car and a gun-gasser.
