Exhaust manifold coating

[Ronald Olds <tr6@pipeline.com>]

Does any one have any experience with getting an exhaust manifold coated? I
am planning on getting mine done for the TD and have found three companies
on the net. They are:

Jet-Hot
LoKo
HPC

Has anyone had experience with any of these companies or know of another
one. What color should the TD manifold be?

Thanks for the help,
Ron Olds
