All coating the outside of the housing will do is make sure the turbine housing cant radiate heat into the engine bay, because most of the heat will be trapped inside the material.
imho, from a logical standpoint if you are going to coat it at all coat the inside.
input from others welcome.

I was quoting super bleeder and missed it said turbine housing.
Regardless, you got a ton of heat and pressure depending on your boost levels so I would have to say not a good idea. Anything in the intake tract or the exhaust tract that has has an opportunity to become free is not a good idea to have. Besides if the outside of the turbo is coated, there is no use of coating the inside, wheres the heat gonna go besides through the exhaust turbine!
