Next, slide one of the shrink sleeves over the end of the wire,positioning it over the boot and sleeve. While a match or lighter willshrink the sleeve, a heat gun is the best bet for "shrinking theshrink." An open flame, such as a match, will get the job done but, inmany cases, far too quickly. The result is often a heavily distorted orburned heat shrink. If you use a heat gun, simply apply heat and watchthe shrink do its thing. If any unsightly wrinkles are evident, applymore localized heat. Be forewarned: You can go too far with a shrink.When it looks right, stop! Too much heat will distort the shrink-sleevematerial.
