i'm mostly done with the ee3. the weathering isn't complete, but since i'm trooping on wednesday with it, i wanted the paint to have a good amount of time to dry. it needs more rust, and will probably get it later this week.
the base paint is rustoleum satin black. the greyish muck is a mix of black and grey acrylic. i poured out a bunch of each of them onto my little palette. instead of blending them together, i just dipped the brush into them both at random, and daubed it on. this led to the mottled effect you see in that pic.
there are tiny bits of rusty brown here and there, but not much yet.
and here it is next to my sci-fire one:

i started off trying to be really exact with weathering, but then i realized that this is going to get beaten and repainted many, many times... so that would sorta be pointless. instead i'm going for similar in style to the movie, rather than 100% accurate.
the hyperfirm used to be pretty detailed in its weathering, but over time it devolved into just that misty brown color, due to numerous touchups.
