Basically go to youtube and search for chipping or rust or mud and models.

What type of models are you doing. I had looked at many youtube videos recently.

route62, thanks for the info

That looks stunning.

I just finished a model using oil paints to weather it.  I watched several videos on YouTube, both armor and aircraftt oil paint weathering.  I was able to achive very convincing results.  Do a search for scale model oil paint weathering in you tube.

Here is a pic of the exhaust stains I was able accomplish using this technique.
