heat shrinking, do I have to buy another tool now? Options

[machina]

Can I use a blow dryer or flame maybe to heatshrink the electrical connectors or do I have to buy another new tool? (heat gun)

My experience is that a Hair Dryer will not work. It simply
doesn't generate enough heat.

Matches can be used but I have a difficult time with the short burn time
and keeping from burning my fingers.
They also tend to toss out alot of carbon.

I've used heat guns before and they work great but many times
especially for repairs in the car, the car may be some distance
from power. Requiring the use of extension cord.

So I now use a fireplace/grill lighter. It is basically a fancy butane
lighter with a really long nose that keeps the flames away from
your hand.
If you first light the flame and quickly move it back and forth
under the shrink tubing just enough to cause the shrink it will work really
well and not put too much carbon on the tubing.
You must be careful not to linger too long or you will melt the tubing
or the coating on the wire.
