Everyone else thinks it is great?
Fantastic reviews and a good price so bought this for a few jobs I've been meaning to do around the house. Don't know if I got a bad batch, but I couldn't be more disappointed.Used it to stick a rubber trim to plastic and a week later I could pull it apart with my fingers. Used it to seal a leaking joint on a plastic pipe and the water keeps leaking. The only good thing was that it was easy to remove as it doesn't stick to anything. Amazon gave me a refund so it is only my time that has been wasted.
