I working bit by bit to restore my 2007 Prius. 1. Rubber tubing by the hatch latch is corroding. Can this be fixed at all? 2. Panel in the rear hatch is missing. Is there a part number for this? 3. The Power button paint is worn through and the Volume text is missing. I can probably cut out the words "Volume" on a craft cutter, but can I replace this button? Super minor, but wondering.
