These are the markers I'm using. They're from Zeon, Basic, Real Touch and probably my the Advanced set, but I can't remember exactly.
I've got an old brush that I don't plan on using in future, so what I do is apply some marker, then dab it with the brush, or wipe with my finger.
Obviously the brown on the right gets the most use, and the real touch is great for adding dirt and grime (like under vents). White adds some highlights and also, if you leave it on a bit longer so it sets, can look like old paint that's started separating. Grey and black are almost exclusively for adding some tone here and there.
What really made it look good, I think, was panel lining with the black fine tip that comes with the basic set. Because it's so thick and basically a felt tip, you get a really nice finish and it makes the panels look like they're slightly separated, perfect for the rusty weathered look.
