What kind of raddle can black paint do you use to black-out engine parts and accessories that will last awhile?

I always liked the wrinkle finish but I'm not 100% sure if they make it in High Heat.

 

I've used some sandpaper to rough up the chrome, then etching primer, followed by a good grade spray paint. Works good.

 

You can use Duplicolor engine enamel. But whatever paint you choose, prep the area well like using wax/grease remover and scuffing the surface.
