Painting a Front Catalytic Converter — Bad Idea or Not?

Motor Vehicle Maintenance & Repair Asked by Igor Soloydenko on June 2, 2021

I need to replace the front catalytic converter on my 2006 Suzuki Aerio. The part came in bare metal, no paint or any coating is visible or possible to feel on the surface.

Should I not paint it to avoid messing with the heat dissipation properties? Or should I paint the part to prevent rusting? If so, what color — White or black?
