The zinc-plated steel used in some panels of the vehicle requires different repair techniques than for ordinary mild steel.

1. Before spot welding the zinc-plated steel, remove the paint from both sides of the flange to be welded. Apply sealer to the flange after welding.

NOTE: Seal the sanded surfaces thoroughly to prevent rust.

WARNING: To prevent eye injury, wear goggles or safety glasses whenever sanding, cutting or grinding.

2. The electric continuity properties of zinc-plated steel is different from ordinary steel. When spot welding, increase the current by 10-20%, or increase the resistance welding time. Also increase the number of weld spots by 20-30%.

NOTE: The MIG welding procedures for zinc-plated steel are the same as for ordinary steel plate.

WARNING: To prevent eye injury and burns when welding, wear an approved welding helmet, gloves and safety shoes.

3. Before applying putty or body filler to the zinc-plated steel, sand the zinc plating thoroughly to promote adhesion and prevent blistering.

NOTE: Use only epoxy-based putties and fillers on zinc-plated steel. Follow the manufacturer’s specification.
