I have a question regarding the center section of a 70 Challenger R/T grill. I have been told the correct finish on the honeycomb section was an argent paint. I suspect that is incorrect. I thought the finish was a straight aluminum anodize. I have also seen some grills (not necessarily on an R/T) on which the honeycomb was black. Was the black finish or the argent finish ever correct for any model? What in fact is correct for the R/T?
