Rust, Streaks and Shadows

I know for a fact they're achieved by using a brush, not an airbrush. Any weathering can be done using many weathering techniques like washes, pigments, hairspray techniques, etc...

As mentioned, this is best achieved with a brush rather than an airbrush. You might want to look beyond tamiya paints for weathering. For weathering you really wnat a differant medium to your paint. So oil's/enamels on Acrylic and Acrylic on enamels.

I also prefer a brush for rust streaks.  The only time I use an airbrush for rust is if I am simulating very light rust which is still mostly subsurface and I just want a very slight rust tint to show.  The rust streaks can be either normal paint thinning ratios, for a heavy, local streaks, or a water-streaked rust effect done with a very thin wash. I often put the later over the former.

Don't ask me - I don't know **** from Shinola! Hell, I might even get your house burned down, get you deported, or even killed!! So don't listen to anything I have to say. If you really want a good laugh, look at my four foot X-wing build in the sci-fi thread. It's a scream!
