I recently read an article about the paint used on the mode! T Fords. A fellow bought an old garage that had been a Ford garage at some point in it's past. Among the stuff they found was some new old stock cans of OEM Ford paint in their original containers. The color marked on those can were indicated as being blue,green and brown. They decided to open the cans and following the instructions on the cans they painted some parts as a test. When the paint dried guess what happened.... All parts dried BLACK. A!most funny in a way. From what I have read Mr.Ford actually preferred using black because it dried the quickest thus shortening factory build time. No proof of that of course so possibly only a urban myth.
