I just read the story “The why and how of weathering powders” in FSM February 2010, and I have a couple of additional ideas:

1. Apply the pigments with a smaller, round brush, tap them onto the model, and work them into flat paint with a wider flat brush. This gives very fine control for subtle effects.

2. If you use acrylics for painting, mix pigments with paint thinner to a milky consistency. Then hold the brush close to the model and shoot air through your airbrush for realistic mud splatters.
