How to fix scratches in paint and in screen

There are many small scratches in the screen and paint of this camera.

1. How could I fix the scratches in the paint? (I’m thinking either a car touch up paint, or taping the buttons and screen and spray painting it.) Would one of these work better or should I do something else.

1. And how could I fix the scratches on the screen? The screen still works, so I wouldn’t have to replace it but is there a way just to polish it out?

Thank You So Much!
