Hi all...hope you all had a great Holiday!

Years ago when I built up an ultralight I owned I wanted to make my muffler look better and after some research I sent it off to a company, (I for the life of me cannot remember the name) and had it ceramic coated. It was supposed to make the muffler (from a 582 Rotax) last longer.

I know that there are some very knowledgeable people on this forum and wanted to see what you all could offer in the way of information on coatings like these. How does a coating like that work? Is it reflecting heat, or what? What does a coating (mine was inside and out) do as far as cooling? I know that some of you will have some info or links and I would appreciate anything you could offer. No specific application yet.

The product looks very interesting.
But if you paint the manifold dont you think you could overheat the engine block as the heat wont be able to dissipate. I suppose not all the heat energy will be able to leave the system thru the exhaust gases.

Daryl,
 
 
Typically the ceramic coating would be for aesthetics. Keeps the thing from rusting. However there are some benefits from the coating, namely, it keeps the heat inside the exhaust pipe. If you have a tuned exhaust, then you want to keep it hot as the efficiency of the tuning changes with the exhaust pipe temp. Also if you run the pipe inside the plane at any point, less heat would be conducted to the airframe and you.
