I finished two PsiCorp Shadow Hunters this week and posted a picture of the two of them at Flickr:

I pretty much used the same technique as I have with other Shadow-like ships:

1. Spray prime with black;
2. Paint with several coats of Floquil NATO Black;
3. Apply a wash of silver multiple times.

I cannot list the paint/water ratio I used, since I adjusted it to be more silver between each coat.  I think I applied at least four coats.  I am more satisfied with this result than what I achieved with the other Shadow ships since the silver is more noticeable.  I photographed it under florescent lights so the lighting conditions aren't the best.
