Reading the Maya user manual, I see a page about the carPaint shading node which my Maya 2018 doesn't appear to have? Am I missing something? Thanks!

Arnold plugins for the various supported 3D DCC applications are generally released independent of the host applications, and usually more often. The Car Paint shader released with the Arnold 5.0.2 core, and was first shipped with MtoA v2.1.0. To get the latest version go to the Arnold Downloads page here: https://www.solidangle.com/arnold/download/
