@indigo Apparently when stored in the fridge, its shelf live is around 18 months. One project I did was encasing bits of coathanger wire in Sugru & attaching them to double-walled coffee cups as handles. Worked perfectly. Another was to replace four missing rubber feet on a stepladder. I hammered & screwed wood into the hollow legs, covered it in Sugru which I gave a textured finish for grip.
