Cleaning Exhaust Manifold

Question

I would like to clean up my rusty cast iron exhaust manifolds. What is the best coating to use after they have been thoroughly cleaned, ceramic coating, powder coating, or heat resistant paint to withstand temperatures up to 1400 degrees F?

John Canon · Answer

I use Tremclad High Heat Enamel in spray can. It is rated to 1200F. The flat black dissipates the heat into the engine compartment, while the flat white holds the heat in, allowing the O2 sensor and catalytic to get up to operating temp more quickly.
