A conductive molding compound is provided that is amenable to receiving a highly uniform automotive surface skin quality surface gloss paint coating via electrostatic painting techniques without resort to a conductive priming step. A low density molding compound formulation is provided that includes a thermoset cross-linkable unsaturated polyester, a low profile additive package containing a maleic anhydride copolymer, microspheroids, and an amount of between 0.3 and 3 weight percent of the formulation exclusive of fiber filler of high surface area conductive carbon black particulate. The carbon black is dispersed in at least one of the unsaturated polyester and the low profile additive to produce a cured panel having a surface resistivity value of between 1x10 5 Ω and 1x10 8 Ω, and a Diffracto analysis D number of less than 100 when cured against a mold platen having a Diffracto analysis D number of 25. A process for producing a panel is provided.
