Also, thanks for the pics and info! I've moved onto the core body and bed for now and plan to revisit the wheels when I move onto details.
There are SOOOO many different ways that you can do rust and weathering on models. It's really easy to get overwhelmed by all the different techniques. You have different methods of simply painting rust, then you have weathering powders, oil paint mixtures, and the "hairspray method".
What I do is pretty simple, and I think it looks good enough for my Ork models, and it's what is pictured above, so you have a pretty good idea of what it looks like.
I take a light-brown color, like "Tau Light Ocre", or maybe sometimes a darker brown. I'll just sort of paint the brown over the areas that I want to be rusty. Then what I do is I do a 50/50 mix of orange and that brown color. Then I sort of use the end of my brush as a sponge - I don't really paint I just poke the brown areas, and let the the orange blob randomly there. Don't put too much paint on your brush when you do this, so it's not too thick. Then when I'm done with that I do the same thing, only with pure orange this time, and with even less paint.
When I'm done with that, sometimes I'll wash it with Nuln Oil, and sometimes I'll then drybrush it with a metallic silver color.
