Corrosion prevention

Factory treatments
During production, vehicle bodies are treated with the following anti-corrosion materials:

l

A PVC-based underbody sealer which is sprayed onto the underside of the main floor, rear floor, front and rear 
wheelarches and the front valance assembly;

l

An application of cavity wax which is sprayed into the sill panels, 'A' post, 'B-C' post, fuel filler aperture, body rear 
panel and the lower areas of the door panels;

l

A coating of underbody wax which is applied to the entire underbody inboard of the sill vertical flanges, and 
covers all moving and flexible components EXCEPT for wheels, tyres, brakes and exhaust;

l

A coat of protective wax applied to the engine bay area.

Whenever body repairs are carried out, ensure the anti-corrosion materials in the affected area are repaired or 
renewed as necessary using the approved materials.

 BODY SEALING MATERIALS, MATERIALS AND APPLICATIONS, Approved materials.

Precautions during body repairs and handling
Take care when handling the vehicle in the workshop. Underbody sealers, seam sealers, underbody wax and body 
panels may be damaged if the vehicle is carelessly lifted.

 LIFTING AND TOWING, LIFTING.

Proprietary anti-corrosion treatments
The application of proprietary anti-corrosion treatments, in addition to the factory-applied treatment, could invalidate 
the Corrosion Warranty and should be discouraged. This does not apply to Rover approved, compatible, preservative 
waxes which may be applied on top of existing coatings.

Fitting approved accessories
When fitting accessories ensure that the vehicle's corrosion protection is not affected, either by breaking the protective 
coating or by introducing a moisture trap.

Do not screw self-tapping screws directly into body panels. Fit suitable plastic inserts to the panel beforehand. Always 
ensure that the edges of holes drilled into panels, chassis members and other body parts are protected with a suitable 
zinc rich or acid etch primer, and follow with a protective wax coating brushed onto the surrounding area.

Do not attach painted metal surfaces of any accessory directly to the vehicle's bodywork unless suitably protected. 
Where metal faces are bolted together always interpose a suitable interface material such as weldable zinc rich 
primer, extruded strip, or zinc tape.

Steam cleaning and dewaxing 
Due to the high temperatures generated by steam cleaning equipment, there is a risk that certain trim components 
could be damaged and some adhesives and corrosion prevention materials softened or liquified.

Adjust the equipment so that the nozzle temperature does not exceed 90

°

 C (194

°

 F). Take care not to allow the steam 

jet to dwell on one area, and keep the nozzle at least 300 mm (11.811 in) from panel surfaces.

DO NOT remove wax or lacquer from underbody or underbonnet areas during repairs. Should it be necessary to 
steam clean these areas, apply a new coating of wax or underbody protection as soon as possible.

Inspections during maintenance servicing
It is a requirement of the Corrosion Warranty that the vehicle body is checked for corrosion by an authorised Land 
Rover Dealer at least once a year, to ensure that the factory-applied protection remains effective.

Service Job Sheets include the following operations to check bodywork for corrosion:

l

With the vehicle on a lift, carry out visual check of underbody sealer for damage;

l

With the vehicle lowered, inspect exterior paintwork for damage and body panels for corrosion.

It will be necessary for the vehicle to be washed by the Dealer prior to inspection of bodywork if the customer has 
offered the vehicle in a dirty condition.
