Power Armor provides a lot of protection and makes the game much easier. However, the armor breaks after a while and you will have to repair it at one of the Power Armor stations. The first station is found in Sanctuary. Repairs only cost steel, which is easy to come by. You have to go there while inside your Power Armor and put it near the station. Going there without your armor does nothing. Painting it in new colors does not just change the look, but it also provides bonuses such as increased charisma or perception. Upgrading it obviously increases the armor rating, but requires the Science and Armorer perks.
