Isn't there a burning bush in your vicinity?

The problem is that fairly high temperatures are needed, well above what a
lighter or hair dryer put out. Lighters, in particular, will burn the tubing
before shrinking it.

I've had pretty good luck with butane lighters that are turned way down
(a mere flicker of a blue flame) *IF* they're used on fairly small
shrink tubing. Just keep the hot spot moving and pay attention to what
the tube is doing. Works great with 1/16" shrink tube for single pins
but I do imagine it could be a disaster with large diameters.
