primering the door sills & inside of the doors was next, these areas were mostly sanded down to bare metal, just the inner parts of the door that will be covered with the door panels weren't taken to bare metal. I filled all of the holes for the lower carpet panel as the plan right now is to leave them painted, not covered (I can always put a cover on them later if we want too, but it'd be hard to fill the screw holes and paint them if we wanted to ditch the panels later on)
