Flooded heat-shrink is rather more expensive than standard single-wall
but is well worth the cost if you're installing wires which will be
exposed to moisture.

For small projects, I've occasionally sliced strips of hot melt glue stick
and stuck it inside the heatshrink prior to shrinking it. It's not as
convenient as the flooded heatshrink but it has the same effect. It's handy
for automotive splices.
