The cavity preservation with wax already performed at the factory completes the corrosion prevention measures.

No repetition of this preservation work is necessary.

Repair preservation 

After accident repair spray cavities with wax in machined areas. When replacing detachable body components, e.g. front fender, engine hood, doors, trunk lid as well as during welding, riveting and soldering work, also perform repair preservation.

Always apply repair preservation 2-times in succession following a flash-off time of 5 minutes between each application.

After drying, ensure that drain holes are not plugged.

It is important that the wax preservation agent is applied following sealing and paintwork, however, before assembly.

Otherwise paint flaws will occur or installation parts will be soiled with wax.

Replacement bodies should also have preservation agent applied to them after painting 2-times in succession.

Replacement bodyshells top-coated in the factory have already been treated with the standard cavity preservation.

Processing instructions 

The cavities should be dry for preservation. Before commencing preservation work, check the spray pattern from the spraying hose or spray can. The wax must spray uniformly from the openings in a circular pattern.

If necessary protect the interior against wax with film.

Particularly advantageous are nozzles which spray toward the front as well as at an angle toward the rear.

The spraying hose of the hand-held lance must be "stiff". Hoses that tend to roll up are not suitable.

When preserving, insert the spraying hose into the cavities in all directions as far as possible. Spray while slowly inserting and retracting the hose (processing temperature not below +15°C). Clean spray nozzle and spray hose together with spray equipment.
