A quick update and a couple of pictures for showing you my progress with the puffer model:
As you can see, I have overlapped some paint on the AO map, similar to stock camo schemes. Still no diffuse/specular/normal maps though, so no surface features yet (bumps, indents, rust, scratches, stains and details to small to be modelled), but at least you get an idea.
I want this unit to be multi-skinned and I am open to your suggestion on some likely paint schemes on a similar boat.

Does the shadowing look a bit better with the color added?
