Paint for exhaust headers

[Eric Straub <ericst@MICROSOFT.com>]

I know this has been discussed before, but I can't find the email. What 
paint to people recommend for the exhaust header? I bead blasted mine & 
painted it with high a heat aluminum, but I recall someone mentioning that 
ceramic may be a better way to go. If so, where can I get ceramic?  The 
rest of my exhaust is stainless, so it's only the header I'm concerned 
about.
