Ceramic Coatings

[R Mangas]

  That seems really expensive for that coating, which can be bought and used
OTC here:

http://techlinecoatings.com/Exhaust.htm

   I used this on the manifold and downpipe of my turbo Miata; didn't do it
right (put on too thin, maybe?) so it flaked off; the second try (heavier
coat) on the lower half of the dp is holding up better.  There is probably a
benefit to getting professional application, but the major preparatory step
I'd expect from the pro would be dunking my part in thier ex$pensive
vibratory polisher.  How much more is it going to cost to polish the inside
of your header as well as the outside? :) (Hint: zero in my mind...)

  To be fair, I could be wrong about the pro coating vs the OTC stuff, but
if you check out the site you'll see the only obvious difference is the
carrier fluid.


If you want to wait a couple months, I'm going to redo the Miata manifold :)

  hth,
Robert
