High heat paint tips?

So I'm about to embark on a project to retrofit my headlights. I had the idea to paint the shroud of my HID's to match the truck. Similar to this: http://retroshop.us/2009+ F150 - Satin Black - Gloss Reflector - Orbit Shroud/slides/DSC08643.jpg The problem is I think it should be a high temp paint... but it's plastic. I know it sounds stupid, I mean it's plastic right? It can't get too terribly hot. But I'd like some input from someone with more experience.

Regardless, does anyone know of some durable paint that would withstand sunlight and/or the heat produced by the headlights for a good long while? My current assumption is to go with Krylon Fusion. Would I need anything besides some tape to mark off the parts I don't want to paint? Any tips? Common mistakes?

I also want to do the "demon eyes" effect. I would use high temp stuff for that right?

 

FYI standard 35W HIDs generate less heat than halogen bulbs. The brighter 55W HIDs generate about the same amount of heat as halogen.

 

I haven't decided which I want to go with yet though. I've got an extra set of headlights I'm going to crack open and do the BHLM, while I order the retrofit kit. I'd like for the paint to be acceptable for both 35 & 55w.
