Cosmo and list. I believe this discussion thread started about ceramic 
coating. JetHot, good company, is known for its quality 
coating.This,however, is normally an "appearance" coating. Nice finish 
and even has some self-healing properties if it is scratched.  However, 
ceramic coating serves a  different purpose. Ceramic coating is 
designedt o retain heat inside the header/manifold/exhaust. Keeping the 
heat inside makes the exhaust gasses flow faster -a good thing when you 
are trying to make power. A side perk is heat retention inside the 
header means less heat under the hood (bonnet). Ceramic coating gives a 
nice external appearance but not quite as nice as the JetHot or similar 
non-ceramic coatings. Ted
