Hey Norm, i started with vinyl masks from aztec dummy, which gives you 2 colours, then after you've done that, you would normally continue with multiple layers of masking and new colours which is what i did with the 1701-A (3 layers, 4 colours). I decided this time to mask the primary colour and use the detailed decals as well to give more definition and surface variation. I'm pretty happy with the result so far the only drawback with the decals is that i can't vary the surfaces between matt, gloss and saturn finishes which star trek ships do so well on screen.
