An update on this project. The decals arrived and I did up two 40' units. A few issues that need fixing, some of the minor lettering is not scaled quite right.
I painted two versions to aim for the range of colors that the containers appear in my neck of the woods. The lighter version is Poly Scale Penn Central Green and Reefer White, and the darker has some ATSF Blue added. I prefer the green tone of the darker version, but both are much closer to reality than what I have seen of the (unavailable) versions sold by DI.
Still getting the big logo to settle down with Micro Sol...
