After a month or two, it no longer sticks. I had a simple application, tape some small telephone wires to the inside of a new cabinet. The telephone jack ended up inside a cabinet and I mounted the phone on the outside. I routed the wires in the cabinet and used 4-5 pieces of Gorilla tape to hold the wires. It has been 1-2 months and the tape is no longer sticking to the cabinet walls. Keep in mind these are very small telephone wires. I have found this to be true a number of times where after 1-3 months, the tape simply no longer sticks to whatever you applied the tape to. I've used other heavy duty black tape such as Nashua or 3M and they stick much better and a lot longer.
