Thanks for all the comments guys I don't have an airbrush, nor the skill to use one, so it was just Tamiya rattle cans and Tamiya Panel Line detail.  The gray is Tamiya Light Gray (IJN).  I was debating to go with the anime correct stark white (like the space shuttles) or real-world aircraft like the F14.  I ended up going with the latter.  For the Strike Packs, I just went with Navy Blue (US Navy).  Turned out to be almost a cross between the Yamato 1/48 and Bandai DX 1/48 color
