Restoring Dart side trim...??

Although I'm not fond of it, (I'm NOT welding up the holes) I need to restore the side trim for a 69 Dart Custom 2-door.

What's safe to blast the black paint off? Soda ash? Glass bead??

Any type of special hammer you'd use to "massage" the small dings???

Lastly, what does one polish with to bring it back?

Thanks!
