I had my entire exhaust system (started with a new 88 2.1L Digifant exhaust
system), the cylinder head sealing surface (eliminates the head corrosion
problem), combustion chamber, piston tops, exhaust port, exhaust valve
radius(the underside exposed to the exhaust port) and valve tops.  I had
Swain Tech coat ALL parts that will  touch heat except the muffler (using
the clamp strips would cause damage, plus I did not know if I would like the
muffler yet) and tail pipe (it was not finished yet).  I wrapped the muffler
in a fiberglass heat containing wrap.

The engine compartment temps have been dropped to the point that after a 100
mile trip at 70mph in 90 degree heat, the alternator is warm to slightly hot
(in cooler weather I can put my hand on the alternator and leave it.  It is
warm)

The main purpose of the ceramic coating is to protect the heads from
corrosion, the engine from the additional heat developed from my performance
modifications and drop engine compartment temps to enable the rubber parts
to last longer and be subjected to less heat stress. The additional power
was a bonus.

Look for an upcoming article about ceramic coatings, featuring my 1988 VW
Wolfsburg Vanagon, in Hot VWs mag.

The total cost for all the coatings were about @$700.  The savings on labor
helped me to affort all the extras. Plus I only want to build my engine ONCE
and do what it take to do the engine right.
