I decided not to get too crazy with it, so I didn't worry about how the original model was a true commercial chassis length. And I decided to keep the original Superior rear door, because I thought it would look better than anything I tried to scribe in at that tiny scale.
After I had the body filler sanded to the shape I wanted, I marked where I would add small pieces of round styrene rod for the lights and scoop stretcher box.
After this was finished, I built the car up on a temporary clay platform for when I poured Part 1 or my two part mold.
With my two-part mold finished I was ready to cast the new resin body.
After priming and painting the car white, I taped off the areas that would be painted orange.
With the orange stripe painted on, I was ready to stick on the water-slide decals that I printed and paint the tunnel lights and rear bumper silver.
With the lights painted and the decals added, I was ready to spray on some clear coat and reassemble the body and chassis.
