Are you using antiseize on your turbocharger hardware that was designed for use on "Chebby 350" applications? Finding it doesn't really do anything but burn off after the first heat cylce? Yea, we did too, so we found a solution.
Rated to 2400F, more than your exhaust manifold or turbo will ever see, will keep threads from galling and fasteners from seizing. Contains no metals (becuase most don't withstand these temps), safe for all types of metals. Military grade.
