With the arms apart, I sanded and cleaned the rust pieces (they have to be reused.) I then sprayed them with a rust paint and let them dry for a day. Once they were dry, I painted them with some flat black model paint. I didn't remove the plastic sliders (I couldn't get them apart!
) so I kept moving their position so that I got paint on all the surfaces (I HATE rust!)
I forgot to take a pic this step, but you need to reassemble the arms exactly as they were originally (they are only supposed to go one way!) I used the new LMC arms and retainer clips they provided. Look at your retainer clips when you get them, they're only supposed to go one way, you can tell better when you see them what I mean.
*I'm sorry some of these came out blurry
