I havent tried it on the bus but Eastwood makes a stainless steel exhaust manifold paint that I have used on some of the old cars. you have to have the part really clean and you brush it on and bake it. we used an old oven but you could just start the engine and go run it so it gets up to temp. It does stink really bad when it cooks but after that I have had manifolds that still looked great after years.

About exhaust paint: (These are one of many sources or do your own searching)

Bottom line is that any paint that needs to bake on is NOT to OVER bake or will result burned into flakey condition.
So follow its direction carefully. All paint come with liquid state to apply on surface...that liquid will boil if heating too quickly before it can cure. So slow drying with slow low to high heat will be cured properly.

About engine paint:
Use manufacturing's engine paint or this:

Make sure you final wash it with degreaser such as Grease Lightning®, Oil Eater®, Right Stuff® or any other equivalent degreaser. Rinse thoroughly and run engine till warmed to remove moisture and let it cool to about 60°F range before painting. You can paint at higher temp surface and it will dry quicker but to cause weaker bonding for longer life.

In the mean time apply a light coat of chassis grease onto any label or identification plates. Easier and better than taping as well it could remove OEM background paint.

Caution....After painted...do not remove any grease from label until a week of curing. Otherwise you can damage new paint around it.

If you have any place that bare metal, you need to prime it and dry thoroughly before next the step.

Caution to always remember....never at anywhere in open or enclosed building or shop that has a future painting project in the making that having a spray can of SILCONE on shelf or been spray onto something to cause a near permanent coating onto future painting project. All automotive manufacturing banded can of spray-silicone on site. Very heavy fine or lose your job. Paint will not bond with silicone on surface.....the only way to remove it best is to grind it off. You can clean it with Freon but almost never the same cleaned surface as before.

Just want you to know to save your time & money if you have not known the silicone can do to the unwanted situation.

Hi Temp exhaust manifold paint has been around  for a long time. I like the ceramic stuff. I use it on the insides of  my big truck Y pipes and elbows and instead of replacing them every 5 years, they last almost forever.

Thanks NJT 5573
Ceramic is even better yet for turbo which gets hotter than natural atmosphere breathing engine exhaust. Cost more.

I haven't had excellent luck with car exhaust manifolds, but as for painting the engines themselves, I have had great success with standard automotive paints applied with a spray gun.  I have only used single stage paints for this.  Base coat - clear coat would probably be overkill.  The spray can stuff (high temp engine paint) from most auto parts stores has never held it's color and doesn't hold up against degreasers, let alone power washers.  Hope this helps!
