A hole may be drilled in a suitable place for areas which are not accessible for the
application of cavity wax. The diameter depends on the size of plugs available. When this is
done it is vital to make sure that no drilling swarf remains in the cavity (rust will form if any
remains). The edge of the hole must be treated with cavity wax. Finally close with a plug
and seal with underseal.
Only on components with clinched flange edges:
After painting, the inner clinched flange edge must be sealed as far as is possible with
cavity wax. For this, the repaired component should be positioned upright and corrosion
protection wax sprayed into the water drainage holes and/or the thread holes for the hinges
in both directions (50 ml corresponds to about 20 seconds spraying time).
For doors, tilt and turn the component to spread the corrosion protection wax over the
whole edge of the flange.
