I purchased a used exhaust manifold on ebay and it looks to be sprayed with some type of coating or spray... i think its spray painted its a charcoal color... i was just wondering if anyone knew what kind of spray this is? and where i might be able to get some more?

i can upload a picture if needed...

 

It's probably off the shelf 1500/2000 deg. F exhaust manifold paint. VHT as well as a couple other brands are available at most auto parts stores.
