Installation / Application:
  • Difficulty: 4/5
  • Estimated time: 3-6 hours (varies by experience and extent of rust repair)
Suggested Tools:
  • Angle grinder/cut-off wheel
  • MIG or TIG welder (or spot welder where applicable)
  • Clamps and vice grips
  • Hammer and dolly set
  • Drill and bits
  • Wire brush or grinder wheel

Instructions:
  1. Inspect trunk area and mark the extent of rust/damage; remove trunk components as needed (mat, trim, spare tire).
  2. Cut out the damaged panel section back to solid metal using a grinder or cut-off wheel; clean and prepare surrounding edges.
  3. Test-fit the replacement panel, check alignment with adjacent panels and trim, and trim the new panel as required for a precise fit.
  4. Clamp the panel in position and tack-weld at several points to hold fitment; re-check alignment and clearances.
  5. Complete welding with short runs to minimize heat distortion; allow metal to cool between welds.
  6. Grind welds smooth and blend seams as needed; apply a rust inhibitor to all exposed bare metal.
  7. Apply seam sealer to welded joints and seams, then prime and paint the repaired area to match trunk interior.
  8. Reinstall trunk components and inspect the repair for fit, finish and watertight sealing.
