The chart in the Jim Soares 1958 paint article in the Restorer ,lists the exterior paint as Silver Blue, and the interior paint as Blue-Gray. Are these two paints the same, or is the interior a non-metalic paint of a different shade? The PPG Silver Blue Poly paint #2431, that came up when crosschecking the original Silver Blue Metalic on the Dupont 1958 color sheet, is listed as being slightly less blue and having a courser metalic than the original. Have other 58 owners out there found a better match? At this point I'm locked into the PPG system, so switching now is out of the question. Live and learn...
