Like on the Shoprite and Old Spice TYCO cars I just posted, here is my rundown on that;No matter how I try, getting a decent rusty look still eludes me.
With a fine tipped brush and some Burnt Umber oil paint, dab some small spots here and there randomly. Vary the size of the dots, and use multiple fresh dots to make lines, larger patches, ETC.
Next up, use a clean, wide brush to lightly drag down on the oil paint. Some people wet the brush, I personally, do not. I just make sure to wipe the brush off regularly.
Once you are happy with the streaks, not necessarily the texture or color, you can use dark and lighter rust weathering powders to bring the color and texture. What I do, is use the brush applicator that comes in the Tamiya weathering powder kits, and after using an exacto blade to scrape some "powder" from the weathering kit, I lightly dab the brush into the powder, and also lightly dab it onto the oil paint. Alternate the rust colors, don't cover all the oil paint with one weathering powder color.
You can repeat the steps as many times as necessary, however keep in mind, you are building up layers, so don't use too many or it may appear "odd".
As far as other rust applications; Like that Erie Lackwanna gondola I posted before. What is in the gondola, is straight from the bottle, Tamiya Brown Panel Liner. It actually winds up being a fantastic rust color once dried. I use it frequently to highlight details, and build up heavy rust. Multiple applications will layer, as shown inside that gondola.
Another method you can try, just involves using Acrylic paint with water. Wet the model in the area you are working, and randomly apply thinned rust colors to the surface that is level. Once dried, you can achieve multiple rust colors with a random pattern. Then use weathering powders for variation.
