Hi Nino,
I'm sure your mega busy with other projects/factory setup.
Just asking about Genie as you said after putting new GI white down (quote) "I will go over the black lines later ;"
I'm currently doing the same thing and Iv'e been eagerly waiting/following this particular thread, so I can follow/copy, your amazing work.   

Any progress/tips?
Cheers, Paul.

At several stages, I've had to "lock in" my work with a clearcoat. This is time consuming, but it ensure that if I make any mistakes from that point on, I don't mess up the previous work. The black lines are done in sections - I don't like laying down colors and then painting the black line straight over as there can be some bleed into the colours. So I usually leave the lines until last, or in sections "away" from other colors. I use Tamiya adhesive tape to create the lines and curves. I'll document the next stage in more detail !
