Thanks RV, Gino, Jermy and Merlin,
Merlin let me take some better shots and I'll email the to you.
Jeremy, I did both the pre-shade/pinwash technique. What I did for pre-shading was airbrush Model Masters flat black along the panel lines, then slowly built up my base coat, then sprayed on a few coats of Furture floor wax to help the oils flow better. Once it was dry I used Winton oils for the wash. For the panel lines Paynes gray was used. To give it that rust look in spots I used Yellow Ochre and Burnt Sienna, both mixed in different shades. I let the oil wash set for 3 hours then using Q-tips to blend the wash in. I will be doing a feature and this technique soon.
