How To Repair Fallout New Vegas

Repair is a skill in Fallout: New Vegas.

Characteristics

Items can now be repaired to 100% regardless of the player character's current skill. Repair still governs the effectiveness of repairing one item with another, using the same repair efficiency calculation as Fallout 3, but with a static 100% condition limit in place of the skill-based limit.

A higher Repair skill unlocks crafting recipes for different types of ammunition and other gear at reloading benches and workbenches, such as the Weapon repair kit with 50 skill. High Repair also allows one to repair mechanical or electronic world objects (elevators, doors, computers, etc.).

Ways to increase Repair

Dean's Electronics (+3 or +4 with Comprehension)
Logic Co-Processor (+2 depending on Intelligence, a perfect Intelligence of 10 will see no benefit.)

Skilled (+5)

The Repair skill of an NPC dictates the maximum condition they can repair to, based on the same maximum condition formula used in Fallout 3. The total cost to repair is independent of one's Barter and Repair skills and is calculated with this formula:

If repairing an item were to increase its value by 1000 caps, the repair would cost 2000 caps, essentially a 100% overhead.

Notes

Non-player characters will not repair apparel (such as Benny's suit) that has no DT.
Normally, common weapon variants can not be repaired with unique weapons unless the Jury Rigging perk is selected, which can result in the potential loss of these rare items.
Items whose HP values still round to 100% will not offer the option to repair/maintain them, even if they show less than maximum cap value, and will not appear in the list of spare weapons when repairing another of the same type.
