Heat shrink tubing is not that good of a seal against water intrusion. It does not bind with the existing insulation. In OP's case, how is he going to get the heat shrink tubing over the cable without cutting the coax and installing a new f-connector?
FYI, I have used liquid electrical tape on spliced wires, then after it dries slipped on a piece of heat shrink. Doubles the insulation and protection of the splice.
