Having a look at the Puma workshop manual from this thread:

Page 1166 states:

CORROSION PROTECTION

The following information details the materials that are applied during manufacture for corrosion protection.

Factory Treatments

The Defender is treated with the following anti-corrosion materials in production:

  • A PVC based underbody sealer material which is sprayed onto the underfloor, wheel arches and undersill areas.

  • An application of cavity wax which is sprayed into enclosed cavities and box sections.

  • A final coating of underbody wax to cover the complete underfloor including components but excluding brake discs, exhaust system and propeller shafts.

  • A coat of protective lacquer applied to the whole body.

  • A coat of protective wax applied to the engine bay and wheel arch areas.

In addition to the above measures, all steel parts are zinc-coated both sides

I was under the impression that nothing is applied to the puma and didn't think the body was galvanised?

Maybe this manual if referencing Land Rovers past activities.

Any info / conformation would be great.
