Sugru

If you ever need to prototype a physical object or perhaps make repairs, it can be handy to have material that is easily worked. In the past, I've used a product called Shape Lock (it may also be known as friendly plastic). It's not difficult to work with, it sets as quickly as it cools, and it can be reworked easily and indefinitely.

Similar to Shape Lock, there appears to be new product just launched called Sugru that could also prove to be useful for some of the same applications as Shape Lock, and it has applications that Shape Lock does not have since it is adhesive and has a higher operating temperature. The biggest weaknesses compared to Shape Lock (that I see) is that it appears Sugru cannot be reworked once it cures, and Sugru has a relatively narrow 30 minute working time before curing starts.

However if you need the adhesive qualities as well as the higher working temperature ranges, then perhaps that doesn't matter. Also, if you don't need to rework, then Sugru could be worth a look. It's best application may be repairs, but I can see other uses as well.

I haven't had a chance to use Sugru, so caveat emptor, of course.
