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)
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.

When replace only the outer panel, please cut off a necessary range depending on a damage range.
Carefully cut the outer panel so not to damage the reinforcement.
Make sure that butt welding does not heat-affect the reinforcement when welding the outer panel.

Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the finish.
Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension diagram. (See the body dimensions)
Before temporarily installing the new parts, weld the cowl side panel sub-assembly and front pillar reinforcement sub-assembly lower with the standard number of welding points.

Note
Be sure to use Metal active gas (Ar 80% + CO220%) as the shield gas when plug welding.Sufficient weld strength cannot be assured when using 100% CO2shield gas.
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.
