5/9/09:  I shot the underside of the body with a black acrylic enamel.  The purpose of painting the underside of the body is to ensure that it is 100% opaque.  Any thin spots could cause a color anomaly when the car is in full sun.  Here I'm painting the car in my homemade paint booth.  It worked out pretty good, but I learned that I'm not good enough to paint the top coat!
