Use gasket sealant under with, Bar tape, Golf tape, or Baseball Lizard tape, over and it will do the trick. Trim the start and finish at a sharp angle, leaving a long sacrificial narrow strip at the end to tuck and pull. Then trim off it off. For a less pro look use hockey, or field hockey/Lacrosse tape and it will do. One down from that is white surgical tape, which gets dirty in 45 seconds. For the pro look, a quick tap with a soldering iron will seal the deal on the underside.
