ABSTRACT:
The invention relates to a method and apparatus for preventing water from penetrating into a wire harness, the wire harness containing a plurality of electrical wires and being adapted to fit into a grommet and to pass through a hole formed in a vehicle panel. The electrical wires respectively include a section which is to form part of a water-sealed portion. The electrical wires are arranged so that the sections forming part of the water-sealing portion are in parallel in a row. A first water-sealing agent is applied on the sections. A second water-sealing agent is applied over the first water-sealing agent, the second water-sealing agent having a viscosity higher than that of the first water-sealing agent. The parallel arrangement of sections are curled for fitting into the grommet, so as to form the water-sealed portion.
