Anti-corrosion treatment (Freelander 1)

Details of corrosion protection treatment are discussed in the information below.

Factory processing

During the manufacturing process, the car body is treated with the following anti-corrosion materials.

• Application of a protective wax, which is sprayed onto the sill panels and the lower parts of the door panels.
• The PVC-based sealant is sprayed onto the lower surface of the underbody and sills, and onto the front surface of the lower cross member of the control panel.
• Application of a protective mastic to the entire surface of the underbody between the vertical sill panels, covering all moving and elastic components, EXCEPT wheel rims, tires, brakes and exhaust system.
• A layer of protective mastic is applied to the surfaces of the engine compartment.

During each body repair, it is necessary to ensure the restoration of the anti-corrosion coating of the repaired parts using recommended materials.

Spraying protective mastic for cavities

The surfaces to be treated with protective mastic are shown in the following figures. After repair work, always treat the cavities to be repaired with the recommended protective compound. In addition, cavities that were affected by the repair, regardless of whether they were factory treated or not, should also be treated. This includes all box sections, body cavities and internal door cavities. It is permissible to drill additional holes to access cavities, unless these holes are located in load-bearing elements of the body. The edges of these holes should be treated with zinc primer, a protective compound applied with a brush and sealed with rubber plugs upon completion of the work.



Before injecting the protective compound, make sure that the cavities to be treated are free of dirt and foreign substances. If necessary, clean the cavity with compressed air.

The protective compound should be applied AFTER finishing the touch-up and BEFORE installing any decorative or overhead elements.

During the treatment process, ensure that the protective compound covers all flanges and seam areas and that it is applied to all repair areas of both old and newly installed panels.

It should be noted that new body parts and assemblies are supplied with internal cavities already treated with a protective compound. Ensure that these cavities are re-treated after repair.

Reliable cavity treatment is very important. Always follow these rules:

• Complete all touch-up operations before applying the protective coating.
• Before processing, clean the surfaces to be processed and, if necessary, blow out the cavities with compressed air.
• Maintain temperature at 18°C during processing and drying.
• Check the spray cone shape of the cavity treatment equipment.
• Cover all areas that should not be treated and that could be damaged if the protective compound comes into contact with them.
• If there is a risk of contamination from splashing, remove components such as the seat belt retractor.
• Raise the door windows all the way up before treating the inside of the doors.
• Treat body areas usually covered by trim elements before installing these elements.
• Clean the drainage holes of the thresholds and doors after treatment with a protective compound.
• Keep all equipment clean, especially spray nozzles.
