Came acoss this stuff the other week and knew straight away I had to get some. Sugru comes in little sachets and is soft an maleable like Plastecine but cures over night and sets firm.
It says on the packet that it sticks to Aluminium, Steel, Ceramics, Glass, Wood and some fabrics + Plastics. So many things I own were great but the corner broke off, or the clip snapped or the whole thing could just do with tweaking -you know, just that bit where you grab it...?
My first foray is a broken car key.
Their website is fun, and has loads of examples of 'hacks' and repairs uploaded by fans! www.sugru.com
