Corrosion prevention

CORROSION PREVENTION

Factory Treatments

The new Rover 200 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 sill panels and lower inner door panels.
• A final coating of underbody wax to cover the complete underfloor including components but excluding brake discs.
• A coat of protective lacquer or wax applied to the engine bay area.

The information given on the following pages is intended as a guide and shows the areas to be treated with cavity wax, as well as the access holes used during manufacture. Use only recommended materials and application procedures in repair. See INFORMATION, Sealing and corrosion protection.

Underbody Wax

The underbody wax must be reinstated following all repairs affecting floor panels.

CAUTION: Remove old underbody wax completely from a zone extending at least 200mm beyond the area where new underbody sealer is to be applied.

Underbody Sealer

Underfloor areas and sill outer panels are treated with a Plastisol PVC underbody sealer. This material is not suitable for re-treatment.

When repairing areas of underbody sealer, strip the factory-applied underbody sealer back to a suitable break point, ensuring that a clean metal surface is exposed and that the edge of the existing sealer adheres soundly to the panel.

Ensure that blanking plugs and grommets in the floor pan (except those used for wax injection) are fitted before underbody sealer application. Refit any heat-fusible plugs which have been disturbed in repair with the aid of a hot air blower, or replace with rubber grommets.

NOTE: Apply new underbody sealer between primer and surfacer paint operations. Apply seam sealer as necessary before application of underbody sealer.

CAUTION: Ensure that suspension units, wheels, tyres, power unit, driveshafts, exhaust and brakes (including all mounting points) are shielded prior to application of fresh underbody sealer.

Engine Bay Wax

Reinstate all protective engine bay wax disturbed during repairs using an approved material.
