Polishing the door

The door seems like it used to be white, but there was very little paint left. So I decided to just polish it. The framing around the door is pretty rusted. It was white, but I may paint it a silver/aluminum. There is also a bad glop of calk on the top of the window that I need to clean up and replace. The window on the door is kinda frosted. The door handle is original. I am going ot strip the paint on the aluminum above the door so the upper panels match on both sides of the camper
