Please, either don't do this, or be very, very careful if you coat the
inside housing of your turbo.  A friend and I had done just that in an
attempt to keep it from glowing red under high use - and either we made the
coating too thick or the turbo's tolerances are extremely tight - the
turbine seemed okay when we assembled it, however on the car the thing made
loud noises for a very short amount of time, then we found that the edges
of the impellor had chipped and the inside of the housing was scraped (Jet
Hot actually).

Maybe a really thin coat ? Maybe not, we decided not to try again with the
replacement turbo.  This was on a Mitsu Starion.
