I bought a roll of black gaffer's through a notable MO in this forum some time ago (can't remember how long, but I think it was only 30+ bucks at that time (shows how long it was - now its $40 I believe?).
The problem is, while the gaffer tape used to work very well in the past, I realise that recently, its starting not to be sticky anymore. I'm not talking about tape which I've used before, but tape which is still new on the roll.
What I'm referring to is when I now cut a new piece of tape from that same old roll, and try to stick it on something, after some time, it will start to fall off or unstick itself - this is quite strange considering that gaffer's tape is supposed to be strong.
I used gaffer's tape to stick down some extra wires in the interior of my car, and by itself, I can see the gaffer's tape unstick itself even after a few days. There is no stress on the tape which may test the strength of the glue - its just a simple sticking on a surface.
Anyone with similar experiences? Or does gaffer tape have an expiry date that must be used or else its no longer sticky.
