Armor repair can be a tricky process, but it doesn't have to be. With the right tools and knowledge, you can easily repair your armor on the ground. There are two main items you can use to repair your armor: armor glue and super armor glue. Both of these items require you to be in front of a workbench to craft them.
When you hover your mouse over a salesman, they should give you an anvil symbol. This indicates that they have the ability to repair equipment. When you open the supplier window, there will be an anvil button at the bottom. This is where you can pay for equipment repairs.
It's important to note that not all sellers repair equipment, so make sure to look for the anvil symbol when hovering your mouse over them. Once you have the necessary items, place your craft wheel on the floor and put the damaged items you want to repair on the grinding wheel selection item. Your new and improved item will then be manufactured. To repair armor, go to your inventory and select the piece of armor you want to repair.
Press R1 and you should see a 'Repair Armor' option in the menu. You can then choose to repair all damaged items (which can be expensive) or just one item by selecting it and pressing E (or the equivalent of the platform). The durability of the repaired item is equal to the sum of the durability of the old items plus a “repair bonus” of 5% of the item's maximum uses, up to a limit of the maximum durability of that item. You can also use a gunsmith's kit to repair your armor, a blacksmith's kit to repair your weapons, and a tailor's kit to fix your clothes.
However, keep in mind that paying for repairs can add up quickly, especially if you have high-quality equipment.Finally, it's important to note that not all items can be repaired with a unit repair item. Everything not listed above must be repaired by consuming another instance of itself.
