Seriously, I second what Matt said, as I use artist charcoal sticks for weathering masks. You can apply the charcoal directly to the mask and blend in with your fingers....or rub the charcoal on your finger tips and rub/blend in onto the mask for a less subtle approach. Works surprisingly well. In the past, I have also used dirt/soil on my rotted masks.
My name is Marcus its cool lol and i agree artist charcoal gives AMAZING results. Also it comes off with water so as long as you haven't sealed it you can take some away, add more, whatever.
