I had a Bonnie Gray sample made from the paint code ford1 posted above about a year ago. It is definitely the wrong color. It is a straight gray, not a gray with a greenish tint. I had the paint place make a sample of Bonnie Gray in Dupont ChromaPriemer and it was the correct color and matched the MAFCA Paint and Finish Guide. Beware, if you decide to use PPG paints.
