Can you use gorilla glue to fix an Xbox 360 game disc?
No, you cannot fix physical damage to disk with glue. From wikipedia:
CD data is represented as tiny indentations known as "pits", encoded in a spiral track moulded into the top of the polycarbonate layer. The areas between pits are known as "lands". Each pit is approximately 100 nm deep by 500 nm wide, and varies from 850 nm to 3.5 µm in length
As you see matters are too small to operate without special equipment.
