What's a good coating for exhaust manifolds???

Hey guys and gals... I'm doing some work on one of my cars and need to clean up the exhaust manifolds...
I've seen a few threads on coatings people use for the exhaust manifolds and am wondering what works best... I'm looking for something that will look good and last a long time in that hot environment...

What have you used, how has it worked out, and pics if you have them....
