I've used it for a few other uses as well - some of them well off the beaten track!

As a locksmith, I have a key casting kit, lets me take an impression of the key to form a mould and make a exact copy of said key! Right out of the CIA playbook, eh?

I've also cast nuts and bolts from it, using two-part silicone to make a mould, making fasteners that would predictably fail at certain temps. Worked great!
