How to Restore an Exhaust Manifold

I've used something similar. Calyx is a graphite mix that comes in a little jar and I think you could do at least two sets, if not three with it. Rub it on rather than spray it.

Shop around for price.

Anyone ever use slip plate on there manifolds? How to Restore an Exhaust Manifold

Thanks for that link. Neat magazine!

Several years ago, there was an article in one of the muscle car magazines about engine painting and such. The author noted that one "thorn" was the heat riser passage in the intake manifold. Keeping matching paint in that area of the intake. In the end, he said he got the best longevity results when putting some hi-heat pain on that area of the manifold, THEN putting engine color on top of it. Doing this over a period of time so it all got cured well before engine heat happened.

In that orientation, possibly something of that nature might be done with the exhaust manifolds? Then use the "cast blast" spray paint over it. BUT, to me, that paint doesn't look accurate, so a judgment call as to accuracy of the color might be needed. At least with that paint, no need to worry about transferring the graphite into one's skin when later handling the exhaust manifolds. IF that might matter.

In reality, there should be some engine paint overspray on the exhaust manifold upper flange, many times. Which would burn off as the engine ran. So the residue of that burn-off would exist for a while.

I understand the orientation of keeping the cast iron looking nice, unrusted, but I'm wondering how effective using something like C-L-R rust/lime/scale remover might work to keep them looking more "bare" accurate? Not sure how it would act when heated, though. There's a YouTube vid of a guy using it (with red Scotchbrite) to get the surface rust off of an aged paint job, which seemed to work pretty well. I was surprised!

Just some thoughts,

I did not use slip plate but used Eastwoods single pint manifold paint done by brush.
I sandblasted and prepped the manifolds prior to painting and appear to be holding up...
