Introduction to Autobody Technology
Key concepts, tools, processes, and emerging trends for anyone starting in automotive body repair.

1. What Is Autobody Technology?

2. Core Components of the Autobody Workflow

1. Initial Inspection & Estimation

   • Visual examination, diagnostic imaging (e.g., ultrasonic, laser scanning).
   • Create a repair estimate (labor, parts, paint, disposal).

2. Structural Assessment

   • Determine if the frame or unibody is damaged.
   • Use frame alignment machines, laser measuring systems, or computer‑aided measuring (CAM) tools.

3. Disassembly

   • Remove damaged panels, trim, and hardware.
   • Document part numbers and condition for re‑installation.

4. Repair / Replacement

   • Metalworking – welding (MIG, TIG, spot), panel beating, metal stitching.
   • Composite Repair – fiberglass, carbon‑fiber patches, resin infusion.
   • Plastic & Trim – injection‑molded part replacement, heat‑forming.

5. Surface Preparation

   • Cleaning – solvent wipes, pressure washing.
   • Sanding – progressive grit (e.g., 80 → 320) to remove oxidation and old paint.
   • Masking – high‑temperature tapes, paper, and plugs to protect non‑painted areas.

6. Painting & Coating

   • Primer – adhesion promoter, corrosion inhibitor.
   • Basecoat – color-matched pigment (single‑stage or basecoat/clearcoat).
   • Clearcoat – UV‑resistant protective layer.
   • Curing – infrared (IR) lamps, convection ovens, or ambient drying.

7. Finishing & Inspection

   • Wet‑sanding, polishing, and buffing to achieve gloss.
   • Quality checks – thickness gauge, color match (spectrophotometer), clearcoat hardness (pencil test), and final visual inspection.

8. Reassembly & Final Delivery

   • Reinstall trim, hardware, and accessories.
   • Perform a road‑test (if needed) and hand over the vehicle with a warranty summary.
