Okay, so now we're into adding paint and stickers. Psycho and B1b had suggested adding some color to the grey to add depth. I used a blue and a brown in turn, adding small amounts of them to Delta's Drizzle Grey. These went on in wide swaths across the whole of the board.
I want to say the brown was VGC Leather Brown and the blue was from one of the Reaper Triads. I also added highlights using VGC Wolf Grey, VGC Ghost Grey, and VGC Tan and VGC Bone White. Some bare metal was added using VGC Silver.
I carved in some damage on a few places, and using VMC Black for laser scoring.
I really wanted to add warning stripes, but the template I ordered didn't arrive in time. I did make use of the stickers from the various model kits to add some color, and a few decals.
One of the most time-consuming parts was adding the T, I, and partial T for Titan and making it look right. That was one of the high pigment Reaper reds with VGC Orange Fire used for highlights (blended), outlined with a fine-tipped marker pen.
Easter Eggs:
A "Wolverines!" scrawl in Red Dawn-style font.
A Cobra sticker on the side of one of the cases, suitably aged.
A Word of Blake decal on the side of a Falcon, suitably aged and partially removed.
An old-school Comstar logo on the back of one of the cases, left generally intact.
A new-shool Comstar logo with an "anti" circle painted over it, on the side of one of the large plastic greebles.
Another interesting side note: besides the working Falcon sound effects, there's a sound effect generator from the crane truck back behind the one Falcon cockpit. Press the red light, and you get various engine/construction noises.
Upon delivery to GenCon, several parts were found to have not made the trip well. These contributed to a few places that didn't look as nicely done, but were generally fixed by Day 2. Most of the rust effects were added on site.
Overall, I liked how things came out. If I had it to do over again, I'd have ordered more Hexagon sets, at least one more model kit to help fill in a few more gaps, and gotten the warning stripes template earlier so I could add those. I'd probably also have added more battle damage.
