97 Z28 convertible-little black triangle
 

Has anyone tried refinishing that little black triangle piece on the convertible. It's right behind the window. Seems to be made of aluminum or some sort of pot metal. It's glossy black and the one on my drivers side has some chipping/flaking corrosion looking sort of problems. I wondered if it could be removed and stripped or sanded and then repainted?
Appreciate any input!
