- position the vehicle on a lift, dismantle all relevant compo-
nents and trims which may obstruct access to box sections;
- through provisional or drain holes flush inner cavities and
the underbody with warm (40-50°ë) water (Table 8-2) until the
drained water is clean. Do not forget to fully close the windows;
- remove any water penetrated into the passenger or lug-
gage compartments; blow dry with compressed air the areas
where rust inhibitors are going to be applied;
- drive the vehicle into a corrosion treatment booth and posi-
tion it on a lift; spray the relevant rust inhibitor onto the areas
shown in Fig.8-6, Fig.8-7 and Fig.8-8;
- lower the vehicle, wipe off any dirt from the outside body
surfaces with a cloth moistened in white spirit.
Restoring corrosion-proof and sound-proof coat-
ing on underbody and wheel arches
When in service, the vehicle underbody is deteriorated by
loose gravel, sand salt and water.
As a result, undersealant and primer can be damaged and
worn thus encouraging rust.
For the purposes of noise reduction, corrosion protection and
wear resistance, the underbody and chassis arms are factory
treated with PVC plasticate - Plastisol Ñ-11Ä»- of 1-1.5 mm thick-
ness over epoxy ùî-083 primer.
