"Most of the fiberglass body guys suggest that you NOT paint your fiberglass cars a dark color. "

My research tells me that the folks who say that use a cheaper resin that doesn't have an adequate Heat Distortion Factor (HDT). That tells you whether or not your body is going to be stable when it sits in the hot sun. Low temp resins (general purpose) will deform under heat, and the glass cloth pattern can print through the paint, or panels can deform. That's why some body manufacturers recommend that you "sun cure" your car, and/or you not paint it black. The "no dark color guys" probably used a general purpose resin, what I call a "camper shell" quality. Cheap, but not the best for a car - especially a dark one. Bottom line, if the correct resin is used, the car is "cured" when you get it, and you can paint it any color you like. If I bought another 'glass body, I'd ask the manufacturer about the HDT of the resin. If I got a blank stare, I'd go elsewhere.
