I have done a few operations to carbon hoods. Usually we block them with 800 w/d then clear..then repeat. Some times the edges are so crappy that we repair them and shoot the edges of the hood body color and clear the whole hood leaving a center section carbon. That works good during repairs as well. Also, $300 for painting a hood red is actually at the low end of going rate. Stick with base/clear stay away from enamel one stage users.
