  1. REMOVAL

    Symbol Meaning
    B0049EM Remove Weld Points
    B0049FU Cut and Join Location
    B0049G2 Cut Location for Supply Parts

    1. Do not butt weld or heat repair because the heat decreases the strength of areas where ultra high strength steel is used. (See the introduction)

    2. Roughly cut open the panel so that the adhesive can be reached. Cut through the adhesive with a cut chisel to remove the panel.

      Tech Tips

      In cases where the adhesive cannot be removed with a cut chisel, heat the adhesive with an industrial heater gun or gas burner taking care not to cause panel deformation by overheating.

    3. When replace only the outer panel, please cut off a necessary range depending on a damage range.


      1. Carefully cut the outer panel so not to damage the reinforcement.

      2. Make sure that butt welding does not heat-affect the reinforcement when welding the outer panel.

  2. INSTALLATION

    1. Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the finish.

    2. Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension diagram. (See the body dimensions)

    3. Apply adhesive (3MTMAutomixTMPanel Bonding Adhesive #8115).

      Tech Tips


      • Apply a light coat of adhesive around the plug welding points.

      • Apply enough adhesive to the panels.

    5. Before installing a new part, apply body sealer.

      Tech Tips

      Apply body sealer in an even, continuous bead.

    7. After welding, apply the foamed sealing material to the corresponding parts. (See the painting/coating)

    8. After welding, apply body sealer to the corresponding parts. (See the painting/coating)

    9. After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
