Here's an update I'll share, but please keep in mind that I did this test in less than five minutes. With time and more patience I think the results could be acceptable. Right now it's very rough.

So it occurred to me that I have a whole set of fine line art pens, primarily black, brown and red. But a quick trip to Michael's craft store and I was able to locate a fine line white paint pen that's oil based. I gave it a go just to see how it looked at two feet and it's OK. With the extra paint, plus red and black ink pens I have I'm pretty sure I can give my ST white lines that won't look too bad?

You'll notice that the inks are glossy, but after I'm done with the fine tuning I'll paint the ship with a matt preservation liquid, which should remove the shiny quality.
