Alien Epoxy (Fallout 3)

Alien epoxy is an aid item in the Fallout 3 add-on Mothership Zeta.

Uses
It can be used to increase the condition of the currently equipped weapon, up to a maximum of 100%. Earth weapons are extremely rare aboard the ship, so the epoxy is the only alternative to repair weapons brought aboard. The percentage repaired depends on the user's Repair skill:

Since they have no weight, all tubes found can be carried without being over-encumbered. While the effect of one tube may not conform to the table above, it is always possible to increase a weapon's condition to 100% by applying multiple tubes consecutively, regardless of a player character's Repair skill. Alien epoxy cannot repair armor or clothing.

Locations
Alien epoxy comes in tubes; over 100 can be found on the mothership:
 * 16 in the weapons lab
 * 12 in the biological research
 * 10 in the robot assembly
 * Eight in the engine room
 * Five in the living quarters
