Is there anyone in the GTA or Ottawa that does ceramic coating or something similar?
Has anyone here ever had something ceramic coated?
Approximately what does it cost to have the O2 housing and/or Turbine housing coated?

Another question on the same topic, why is it that the outside is always coated?
The way I look at it if the outside is coated the casting still heats up, probably more than without a coating. If the inside were coated it would help keep the heat from soaking into the casting. Would not look, as pretty but would keep more heat in the exhaust passage.

Any comments?
