ceramic coating care

it seems the ceramic coating on my tti headers is bleeding rust i just noticed this tonite while taking a few pics any ideas on how to prevent this. could i spray rust check on them when the car sits a while. would it stain the header when started? or is there any other products out there that could prevent this and what could i use to get this tarnish off? i bet there is a lot of smart detail buffs out there that have this figured out thanks all
