Is there a good manifold paint?

Working on an 8N. Is there a consensus on good manifold paints in a plain finish? Like cast iron finish?
Thank you,
Rick
 
I've used POR15's gray manifold paint, it looked good at first, but after a year or two if flaked off completely on my daily driver.
 
Eastwood used to make a good one. I haven't used it in several years. If what they sell now is like what they used to sell it has to be baked on but it would stay on there.
 
I use JD muffler paint, it will stay gloss black on the intake and turn matte on the exhaust. I have some I did 3 years ago, still looks good. The important thing is to get it painted immediately after blasting, or you will get rust specks in the pits.
 
Prismatic makes a high temp ceramic coating that looks like fresh cast iron. When I was in that line of work I did a number of exhaust manifolds with it, mostly for car show cars but also some daily drivers. Don't know if it is available to the public. There is a place in Wisconsin that can apply it called Premier Powder Coating. High temp paint is a waste of time IMO.
 
I used the same thing old-9 used. Its a very high temperature flame proof header paint made by VHT. its a silica-ceramic coating and is for temps. 1300-2000 degrees. You have to bake it on according to directions.I did the muffler of my Farmall 450 but have not had a chance to see how it holds up because I have stainless steel pipe on tractor right now for pulling.
 
30 years ago VHT held up well for me.
Might still be an excellent product.
I had to bake it in the oven.
 
You don't have to put in oven. It tells you to run engine a certain number of minutes and shut down and let cool then you do this several times before you actually use it normally.
 
Try High Tempt Cast Blast.

Ain't no such thing as exhaust manifold paint that will stick except of maybe a Marine engine's water cooled exhaust.
Chrome plating will usually stick , stay smokth but will change colour .
I was always going to try bead blasting a manifold to a shine. Then give it the entire rifle barrel blueing treatment.
 
I haven't found any that is any good. The best I've used is Rustoleum high temp stove paint however after two years it is allowing the metal to rust through the paint.
 
Since I"ve been retired, I"ve been fixing some
Wisconsin Engines, 2 Cylinders, and V4"s.
I"ve tried a "Valspar", epoxy enamel, which was
ok, but found "Rust-Oleum, Speciality High Heat
Ultra" works best. I always sand blast the
intake and exhaust manifolds, before painting.
I can"t say if an air cooled engine exhaust runs
hotter, or cooler that a water cooled engine.
