Body posts were made of plastic stock tubing and were superglued to the body. I cut the posts to length, screw them to the chassis and check their fit to the body, modifying as necessary, then marking their position through the chassis holes and gluing in place. Once they are fixed remove the chassis and add more glue around the post to body joint to make a really strong bond. Now to the wheels. The Seat 850 wheels are fully chromed, I left the hub caps chrome but painted the surround in the body colour, this transforms the look of the wheel and looks great.
Enamels are easiest to use here.
The body was painted using acrylic car paints. I used bare metal foil to mask the screen when painting the surrounds and to mask the body when painting the interior. I really recommend spending time detailing all the little bits and the driver, it is well worth it.
