Restoring and Protecting Cast Iron Exhaust Manifolds From Rust with Spray Graphite 

No, the graphite color is the only option. Nothing will stick to it. But it stays clean for a long time and can be touched up without looking touched up. It always blends together

@@ReddirtrodzHad bought two cast Iron exhaust manifolds which supposedly came painted with ceramic paint from the factory. I sprayed both of them with CERAKOTE Cobalt high heat color. I am restoring this Chevy Truck. one manifold started rusting in few spots. The other one is still perfect. Looking for a way to stop the rust so I can repaint it. Thank You

@@nicholasvachek5991 not really for that, it wouldn't last.

If you have a rusty manifold, there are several things you can use. Rustsolve, Eastwood Rust Dissolver, or just plain old molasses. You would be surprised at how effect molasses is at removing rust. The rust dissolvers are reusable several times, so it makes it worth it. Just put it in the smallest container you can find, and cover it. 24 hrs later, fresh and clean. Then coat it!

@@Reddirtrodz Thanks! ;) I'm thinking grease and oil will burn off with heat, leaving a great surface for rubbing the graphite into. I'm definitely going to give this a whirl.

So can I just spray this on my rusty manifold without taking it out of my car? Letting it dry over night before I start it?

No need to bake it at all.

Thanks for letting me know! Here is the right link- amzn.to/42Ikgeo

Also curious if it would work on polished stainless steel vs raw stainless steel?

@stizolac it will work, but they will be dark gray. It will stick to raw, polished is going to probably not stick as well. There are other coatings that are better for stainless.

@@Reddirtrodz thanks for the tip

Yes, a little goes a long way.

No, not at all. Dries in 20 minutes, doesnt smell when hot at all.

Then you didnt prep it well and sprayed it over an oily surface. I have this on many, many vehicles, and it works really well.
