Once the freehand is down, here is when you get to play a bit more and be free to make a bit of a mess. Using my grime streaking, I go in with Gryphonne Sepia and from the edges, corners, bolts and a few of the larger paint chips, I streak down along the model a bit. I don’t like to go all the way down the model, just far enough to make it noticeable. The above look took two layers of wash and a bit of heavy attention to the crevices with a big drop of wash painted in to add the depth we skipped out on earlier! With regard to the top of the tank, I don’t streak, but pool around areas like rivets and other details that stick out. Just a quick pool around these details and a wipe off of the raised surface works wonders!
Once the wash is down, you can move on to a plethora of other techniques that all add something extra to the story of your freshly busted up ride!
