That's pretty good. There are a few silver spots, but the majority looks to be black grime. As mentioned, a black wash does the trick, along with a few black bits here and there.
Here are some of the better photos that show what I mean:
:confused Could you please point out on the pics what you mean...you also see green too right?
EDIT: I'm an idiot....I thought you meant the hose attachment Yeah..it's black like Trekker said....and I used some thin aluminum (I got the metal bug) to make the "white" peices on my whipcord housing....looks much better than painting on the details IMHO.
I could use good placing pictures for the whip cord box and flame thrower and all the add ons to the guantlets, to get mine to fit, i have to modify them a little.. like the whip box, it wont fit on the top clamshell and if i put it in the middle it wont open.. so iama have to like trim the clam down and put it on the bottom to compensate.... i could use some more pics or descriptions of where things go.
