Thanks! It's coming along. . .
I did several of the "effects" stages earlier. First up is the smudge/stain on the right side of the dome. This is a subtle feature, done primarily by dry brushing some Tarnished Black, with a few darker areas added.
Next is the "crack repair." I simulated this using a beige/khaki color. After the final clear coat, there will be an additional stage involving some clear orange. That will simulate some of the epoxy that oozed from the crack.
Visible above are the white thumbprints. Whatever the origin, they're visible on screen shots from ESB, so on they go!
Here's a better view.
Finally, I did the fade below the killstripes. This is more evidence of a repair done on the fly during the original paint up. Again, this feature can be seen in screen shots. It's very subtly visible in the above picture, but when the light catches it at a different angle, it pops into view.
Whew! Pretty much all that's left are the "grease stains" on the rear of the helmet, and a final weathering application of a dark wash and some pastels.
The primer on the ears is nice and hard so I can begin detailing those, too. It's getting really close now!
