The insides of a converter are typically a ceramic coated mesh.  I
believe often the coating contains Titanium which "encourages" some of
the partially consumed gases and other the bad stuff in your exhaust to
take a less nasty form.

I've had converters go bad/get clogged.  As a temporary measure I've
knocked out the remnants of the insides of bad ones for the sake of
driving until I could replace it.  The insides are fragile and typically
the outside is a metal that doesn't rust so I'm not certain you'd gain
much by trying to ceramic coat it.  I think they function best after
they've gotten hot but coating it may change it's effective functioning
temp...I'm not sure.

I wouldn't coat it.
