For the most part, it doesn't need it. There are two plastic plugs on the top of the CRT which cover up some screws, those did need retrobriting, but the rest of the casing is painted plastic and metal, the ABS underneath is neither visible nor exposed to UV light. Also the paint is actually scuffed and lightly worn off in a few places, retrobrite won't do anything about that. It either needs new paint, or I need to accept it as patina.
