The present invention provides for a one-pack primer-sealer composition for molded SMC parts such as automotive body panels that significantly reduces paint defects (such as paint pop and cracking defects) in the sealing and automotive OEM finishing operations. The coating composition includes silane and melamine components. The composition is sufficiently stable to be formulated as a one-pack coating composition.
