Unfortunately I didn't take many shots during the final phases of construction, so I'll have to fill in some blanks here.

After applying the plastic primer and flat black spray paint, I added some color by painting the "wires" that were included in the injection molded frame. I then cut a piece of scrap metal to serve as the clamp for the ribbon cable, and added a piece of 30-wire rainbow cable.

Wear marks were added using silver Rub 'n Buff, a technique which I saw Adam Savage use to realistically weather a NERF rifle. This was the first time I tried this technique, and while I got the hang of it pretty quickly, I definitely feel like it's a bit overboard in some spots.

The final step was to order a proton pack sticker kit, which is used to dress up full-size packs. Obviously the scaling was all wrong for most of the stickers, but several of them came in smaller sizes as they were meant to be placed in multiple locations on the big pack. I was also able to cut some down to size, which at least let me put the right color/shape stickers in the right spot, even if the text was incomplete.
