For those saying it's too dark... different products have different looks. The best reviewed Graphite product for this is Slip Plate. Comes in a 12 oz can at NAPA. It has an acetone toluene propane suspension and soaks into the pores of cast iron. It gets lighter with heat cycling and after it dries, if you buff it lightly with a cloth you will be hard pressed to distinguish it from a freshly-cast manifold. Amazing finish, amazing look, and very long lasting!

Did you guys ever have to replace that choke stove tube, inside that exhaust manifold? Seems a lot of them are cracked and the carb will suck up raw exhaust into the choke cap.

Graphite acts as a heat sink, so an exhaust manifold wouldn't be any place I'd spray it. You want the exhaust manifold to be hot, not header hot, but definitely hot.

The only problem I see is that is about 10 shades darker than your clean blasted one sitting next to it.

If the goal is to avoid having rusty manifolds, then you need to consider other methods. My results after cleaning and treating a brand new (non-rusty) manifold using the spray graphite method shown resulted in a completely rusty manifold after the first rainstorm. Unless your vehicle is stored in a temperature-controlled garage and never goes out in the rain, I would not expect this method to prevent rust. It’s nice that you can wipe it down with more graphite to touch it up, but who wants to redo their manifolds every time you drive on a foggy day?

thanks for the tip. im currently doing my manifolds. I wonder if there is any benefit to spraying the interior of the manifolds ??

Hi, I doubt the graphite would last long with direct contact of exhaust gasses, and don;t believe you'd see any real benefit coating the inside. Mark Classic Car Restoration Club

Was the other manifold next to the one you sprayed already treated with the graphite?

Hi Michael, As mentioned in the video, you can clean up and media blast the exhaust manifold like the one shown, or you can simply clean and apply the graphite directly over the rust and cast iron as we did in the video. The manifold we did not apply it to is simply cleaned and blasted cast iron. Mark Classic Car Restoration Club

How long does it usually last ?
@ClassicCarRestorationClub4 жыл бұрын
Hello, How long it lasts depends on many factors: How much you drive it, How hot does your engine run, have you been driving in the rain, etc... For me it seams to last a month or two before I need to touch it up a little with some sprayed on a rag. During a car season I do it once in the spring then touch it up a couple times during the year. Mark Classic Car Restoration Club

Graphite spray washed right off during a mild pressure wash. Waste of money and huge waste of time.
