dust on vehicles

[Corvus]

Hey, I\'m looking for a way to create realistic dust effects on vehicles.

A friend told me to take an old toothbrush, load it with thinned paint and spray it on the vehicle\'s bottom by rubbing the brush with your fingers.

Any other techniques that I might try (I don\'t have an airbrush btw)? Thanks

Check this here link and pigment secrets article. http://www.missing-lynx.com/rareworld.htm

About using pastels and pigments and turpentine to create realistic weathering, including dust. I think i\'ll try it out soon.

I have read about modellers using pastel chalks, and may have an article around here someplace...I\'ll do some digging....

Here is another article about Doc O\'brien\'s Weathering Powders....they look pretty cool.

Number 3 is exactly what I need!

3. This is the typical deep chipped paint effect and it is same that can be seen both in the desert or in Russia. It is an older paint chip when compared with the ones above, so we can cover it with dust or a light layer of mud. It is accomplished inversely that the previous. First we apply the darker colour, and we enrich it with some small dots around it. After that, and always in the center, we apply the ligther orange colour, but without covering the darker base colour on the edges. In the desert Chevrolet truck different examples of this chipped paint type can be seen. Also it could have been done only with darker colours as in the Pill-Box Panther, so we can achieve older and still wet rusty chipped paint. Keep in mind that a paint chip may present different colours if it is dried or still wet, newer or older. A new and dry paint chip will looks orange but an older and wet one will look red brown.
