A little discussion came from this thread about Cerakote and ceramic coating, thought it would be worthwhile having a dedicated topic.

Cerakote seems to have widespread use in the gun coating market, but doesn't seem to have really taken off in automotive as much. The parent company NIC also owns Prismatic Powders, which is a very well known name in that market.
Where it gets interesting for GRMers: Cerakote offers air-cure ceramic coatings, at fairly reasonable cost. $70 per pint, which should cover several manifolds or headers.
COATINGS:
Cerakote also offers a ton of differnt colors and types, their shop site is a little hard to navigate.
These are the air-cure coatings that have 1800*F heat rating:

Glacier Black Example:

APPLICATION:
The application guide below states parts need to be cleaned and blasted with basically anything EXCEPT glass beads, de-gased with a 300*F bake and obviously clean of grease and oils. So prep is essentially the same as with powdercoating. Then it is simply sprayed on with an HVLP with 0.8mm tip:
TESTING:
Regular cerakote holds up very well to corrosion, at least based on what Cerakote is publishing. It would be interesting to see data on long term durability and efficiency of their high temp coatings:

EXAMPLES
I found out about the air cure coating from this channel, he's been around the Mitsubishi Autocross world for a long time and knows his stuff. He used an airbrush detail gun to apply it:
I have some Glacier Black air-cure I need to try out on some turbine housings and manifolds, will report back with results.
