Snake oil too??

[Joe Boucher]

The coating was developed for jet aircraft.  The one indisputable fact is the
retention of heat and it's effect on under hood temps.  Great for motorhomes.
The performance benefit is something I'm not convinced about.  But if you want
your headers to last along time, I'd do it.  You might call around to
powdercoaing places.  If they can do powder coat, they can do the ceramic
coating.  I think the stuff you can buy in JC Whitney is probably the same
stuff.
