I know we probably already covered this, but
what does the forum think about ceramic coated

to be able to coat the inside of the pipe.

We used this on an exhaust system for a pre-war
Aeronca Cheif.  It only had a 65 hp Lycoming, but
we were using the coating for asthetics.  It was
cheaper than stainless, and to fix it all we had to do
was sand off the coating and weld it up.

Would the ceramic coating be good enough to keep
the mild steel from failing?   This would not be for a
boosted engine.

I'd like to see the results.  I'm assuming the pipes are coated inside and
out.  Really the only problem with mild steel is the extreme corrosion at
high temps.  If the coating remains intact then it will probably work.  A
few cracks in the coating and you're probably on your way to pipe cracking.
 I hope no-one is trying to put enough coating on to keep the pipes "cool".
That would take some serious thickness.
