AD_Pickup,
Thanks for asking the question. You caused me to look at my paint chip sheets and find out that I have been incorrectly referring to this color name. Dupont called it Sheen Gray Metallic and Ditzler (now PPG) called it Sheen Gray Poly. Long ago, I must have written these together as Sheen Gray (Metallic) Poly.
I think that you are the first person that has reported that a Dupont Dealer was able to make up a batch of paint from a 47-55 code (maybe other successful people have just not posted their experiences, or I have a bad memory - a good chance of that).
Tim
