uhh... wait are the window surround, grille, and strakes powdercoatable or not? sorry, I'm kind of confused now

and if they ARE able to be powdercoated, would it be more durable the process offered here?
sorry for being such a nuisance

i just want all of the light silver bits on the outside of my car turned black... not talking about the interior here, that is a separate issue. just the exterior bits and pieces
