u can repair it if u have the jury rigging perk, with any other light armor, otherwise i dont think u can and have to get it fixed.
This. With the jury rigging perk, you can repair light armor with any other light armor/clothing, medium with medium and heavy with heavy. Otherwise, you have to get it fixed.
Or perhaps you can have Raul as a companion? As I understand, he'll fix stuff for free if he's tagging along with you?
