Review on XFasten 8 Inch 30 Foot Sealing Patching by Brian Whitmore

Good product for sealing water in places like sinks and pipes. Better than a jar of things drying up. You can also use it to seal air gaps in plastic, for example by inserting plastic sheets between car door panels. It arrives a little broken, making the backing difficult to peel off a bit, but its putty is soft as a result. No problem, if you come across it, you can just redesign it the way you want.
