No, line it up drill the holes set it in postion use a nut with a washer attached, gob some 3M window sealer urethane ribbon around the washer and tighten it. this will prevent water from entering that hole and rusting your deck lid and trunk out. By all means just sand it and prime it black with the rest of the car. Don't worry about that crack, you can't do much but grind it out to a valley and fille it with fiberglass or a two part clay, but its nothing to be worried about.

Do it either way, but if you put rattle can paint on it, you'll just have to strip it off later on.
