I've recommended Calyx to a lot of old-car owners.

In addition to the exhaust manifold, I've used it on other cast iron or rusty items such as leaf springs and brake pedal return spring. Apply with an old toothbrush. Wipe off excess with a rag. No problem with greasy feel, but I don't usually touch the manifold after I apply it.

I bought it from Eckler's.
