Great minds think alike. I have a small vial of iron oxide that should work just fine for this application.

Here's how I paint exhaust on plastic model airplanes:
Paint the exhaust rust color and then dry brush the piece with steel.
It is close enough.
Go down to the local airport and look at the exhaust stack on real airplanes.

Not to get too picky-
WWII or Modern day representation?
I remember in the past seeing some great color photos of Lockheed flights of P-38s showing the exhaust quite well.
Modern day P-38s have the stainless steel around the turbo unpainted while WWII would have been painted. Also todays A/C get a bath more frequently.
Other factor for color will be whether it is run in lean for cross country or combat with high power at a rich mixture.
Tan to almost white for cruise, dark brown for higher power.
Maybe Jack has some color pics.

No problem---get picky if you want.
Let me make myself more clear about what I am talking about.
I am talking about the exhaust stacks and turbo itself, not the particular surface or "stainless steel around the turbo". I am not talking about the exhaust stains on the upper surfaces of the boom, just the exhaust stacks themselves. Don't recall mentioning either the stainless steel surface surrounding the turbo or the exhaust stains in my post.
Tom,
If you want to make a home-made rust pastel for brushing on plastic models, you can use the following method:
Take a piece of steel wool and put in in a cup. Pour in some water until the it just covers the steel wool. Wait about a month and the steel wook will turn to rust. Grind up this rust until it becomes a fine powder. Brushing this metal rust powder on the piece will give it an exhaust type look. This works good if the exhaust stack is steel, not stainless steel. I've used this method with good results. Practice on a scrap piece before using on the actual model.
Good luck with your model building.
