Be careful when performing repair work in the workshop. Underbody sealants, seam sealants, underbody mastic and body panels can be damaged if the car is not lifted carefully.
Anti-corrosion treatment carried out by the owner
Owner-applied rustproofing in addition to factory treatment is not recommended as it will void the vehicle's rustproofing warranty. This does not apply to approved rustproofing waxes that are compatible with and can be applied over the existing coating.
Installation of approved equipment
When installing additional equipment, make sure that the protective anti-corrosion layer has not been damaged in the form of cracks or moisture access to body parts.
Do not screw self-tapping screws directly into body panels. Use suitable plastic inserts for this purpose. When drilling holes in body parts, always treat the edges of the holes with a suitable zinc or phosphoric acid primer and then apply a protective compound around the hole with a brush.
Do not install accessories directly on painted metal surfaces to body panels without prior protective treatment. When joining metal surfaces to each other with bolts, always treat the joint surfaces with zinc primer, place zinc tape between the surfaces or apply a layer of inert material.
Steam cleaning
Due to the high temperatures and pressures that occur during steam cleaning, there is a risk that some adhesives and anti-corrosion materials may soften or melt.
Do not direct the steam jet at one place for a long time and place the equipment nozzle no closer than 300 mm from the body surface.
CAUTION: Do not remove any protective or paint coating from the underbody or engine compartment during repair work.
Check during maintenance
An essential condition for the effective operation of the factory anti-corrosion coating of the body is to have it checked by an authorized Land Rover dealer during scheduled maintenance work.
Repair body damage and panel corrosion found during inspection as early as possible to reduce the area of damage and ensure the effectiveness of the factory protective coating.
Repair of protective coating of the underbody
Each time body repair is carried out, make sure that the sealant and anti-corrosion coating is completely restored. This applies to both damaged areas of the body and to places where the protective coating was affected as a result of an impact or during repair operations.
Before repairing a warped panel, remove the anti-corrosion mastic from the damaged areas. This applies especially to panels coated with protective wax, PVC-based sealant, sound-absorbing fillers, etc.
CAUTION: Do not use an oxy-acetylene torch to remove anti-corrosion coatings. When these coating materials burn, they produce large amounts of gases and smoke.
The most common method for removing sealant is to use a heat gun with a scraper. The high temperatures generated by this equipment can cause smoke to be released, so care must be taken.
Structural adhesive
CAUTION: When separating parts bonded with metal adhesive, it is important not to distort the joint. Gradually heat the joint until the adhesive softens enough to allow the panels to be easily separated. Do not overheat the panels.

NOTE: When spot welding is performed on a joint between parts joined with metal adhesive, the transformer parameters must be carefully selected to obtain a reliable weld.
Metal adhesive, applied to critical seams during factory body assembly. It uses high-temperature application of nitrile phenol-based material. The material bonds two metal surfaces together, while also acting as a sealant to prevent dirt, moisture and gases from entering the joint. This material is not intended for use in body repairs and must be replaced with an approved structural adhesive for load-bearing body components. For specific panel information and to identify areas to apply structural adhesive during repair, refer to the appropriate metal panel removal and installation procedure.
