CAVITY WAX
Cavity wax
After repairs, always re-treat these areas with an approved cavity wax. In addition, treat all interior surfaces which
have been disturbed during repairs whether they have been treated in production or not. This includes all box
members, cavities and door interiors. It is permissible to drill extra holes for access where necessary, provided these
are not positioned in load-bearing members. Ensure that such holes are treated with a suitable zinc rich primer,
brushed with wax and then sealed with a rubber grommet.
Before wax injection, ensure that the cavity to be treated is free from any contamination or foreign matter. Where
necessary, clear out any debris using compressed air.
Ensure that cavity wax is applied AFTER the final paint process and BEFORE refitting any trim components.
During application, ensure that the wax covers all flange and seam areas and that it is adequately applied to all
repaired areas of both new and existing panels.
It should be noted that new panel assemblies and complete body shells are supplied without wax injection treatment.
Ensure that such treatment is carried out after repairs.
Effective cavity wax protection is vital. Always observe the following points:
l
Complete all paint refinish operations before wax application.
l
Clean body panel areas and blow-clean cavities if necessary, before treatment.
l
Maintain a temperature of 18
°
C during application and drying.
l
Check the spray pattern of injection equipment.
l
Mask off all areas not to be wax coated and which could be contaminated by wax overspray.
l
Remove body fixings, such as seat belt retractors, if contamination is at all likely.
l
Move door glasses to fully closed position before treating door interiors.
l
Treat body areas normally covered by trim before refitting items.
l
Check that body and door drain holes are clear after the protective wax has dried.
l
Keep all equipment clean, especially wax injection nozzles.
