What shade of blue was the upper car body. If it was not deminstrator blue can I get help with a formula using Floquil paints
Demonstrator blue is a pretty good choicet. A straight blue would appear to be the right color, but the few color pictures of #499 are neccesarily doctored up, and a tad bit on the light side. I used a model master rattle can, but I’ll look at the floquils for ya.
EDIT: looking at FLoquil, I;d say either the B&M, D&H or Conrail blue would be a good fit. As I said above, the pictures are doctored, so it would be hard for many to prove you wrong in your choice. Of the three, I’d lean to Conrail. It is a darker shade than the later skyblue/white schemes EMD did on the SD45s.
Also, since I’m assuming your using the Microscale decals, the front hood stripe I found to be too short to fit, and at least one picture of the prototype, it’s also missing.
