Doesn't take much, just long enough to get it shrunk down. Rub it, don't hold in one spot, or it could get too hot and melt through.
That's what I usually do. Most times when I use heat shrink it's for a small project and I'm using a pencil soldering iron anyway. Only need one tool for the whole job
