Exhaust Manifold Paint

I'm getting ready to replace the manifolds on my 04 F350. I replaced them 3 years ago with Dorman ones, and now they look like they have been on there for way more than 3 years and just a matter of time before I have an issue with them. I plan on replacing them with genuine Ford manifolds. Is there a recommended paint or coating for exhaust manifolds that won't make them look like rust buckets in just a few short years, and extend there life?

I was wondering the same thing. I have a complete set of Manifold, Studs, Nuts and gaskets on my passenger seat waiting to go in this week.

2008 F-350 5.4. Second time these manifold are being done with FORD parts. Hopefully the FORD SS STUD change, changes the game.

Have them ceramic coated, or go with stainless headers.

Ceramic is better because SS will turn shades of blue near the head.

I decided to get the POR 15 manifold paint. Two coats before I have them installed.

Looking at the ceramic coating it will cost around $200. Not sure about some of the DIY paints as they are heat cured by running the engine. Has anyone had lasting success with the DIY paints?

Well after getting quotes for having a ceramic coating done and the fact I don't want to pay those prices I've decided to try DIY with Cerakote high temp ceramic coating. From looking around the web its the only air cure coating that I found, which will make it easier than having to run the engine for up to an hour to cure most other products. Just waiting on the free color samples to decide which color to go with.

Bake rhem in an oven for a couple of hours before installing, or the paint will get scratched when trying to muscle them in.

Also a big fan of POR-15 stuff---its pretty amazing IMHO. It'll be interesting seeing how that finish holds up over time.

Thanks for the update!

Go to your local high school's art department and see if they have a kiln. You might have to bring a few art supplies as a bribe.

The pass around package of Twizzer's might do the same trick?
