When did it become common not to paint galvanized box car roofs?
Depending on the definition of "common," data from AC&F bills of
materials show that unpainted galvanized roofs became more widely used
starting in 1953. At that time there were a lot of AC&F box cars with
unpainted galvanized roofs except that the seam caps were coated with
black car cement and then over-coated with whatever paint color was
used on the sides, thus giving a striped appearance. There's photo
evidence of General American doing the same thing during the 1950s for
some cars built for Erie and NKP.

As an example, TP&W 626-650 box cars built by AC&F in 1953 had Pullman
Green sides, ends, and roof seam caps. By 1955-1956, the practice of
coating just the seam caps became less common, and the roofs were often
entirely left unpainted. During the mid-late 1950s period
Pullman-Standard's PS-1s also had a smaller percentage of their box
cars coated with black car cement, which had been their standard
practice from 1950 through the early 1950s.
