Before you do anything in this instructable, see Kurt E. Clothier's heat gun reflector. This is awesome as it speeds up the shrinking time tremendously!
I'd actually be happy if you guys would inform me about what you find heat shrink useful for, if it's not already in this instructable. If I like it, and with your permission, I'll post your picture or I'll make one and I will credit you. Thanks Tomdf for the first awesome use for heat shrink, a wire fix! (step 9)
How about we call this an open instructable, where YOU guys get to contribute!
Thanks, and enjoy!
