[s-cars] To ceramic coat or not

[manuelsanchez at starpower.net]

S-heads,

Thanks for the input so far.

I thought I had recently seem some opinions about coating the
inside of components;

1. There was a concern that as the ceramic coating flaked off
or deteriorated, that the bits would lodge in downstream
components, such as the kitties.  Do these coatings
deteriorate quickly, slowly?  How do they deteriorate? Is this
a valid concern?

2. Interior coating is not "smooth" as the uncoated metal,
presumably this would disturb the flow.  Do the benefits of
keeping the heat from the metal outweigh the diturbed gas-flow?

Look forward to your input.
