Volvo 1990 780 Model
The visible rustproofing
The visible (external) rustproofing must be inspected by an authorized Volvo dealer at least once a year.
Consult your Warranty Information booklet for details of Volvo's Eight Year Corrosion Protection
Warranty.
If it is necessary to touch-up the rustproofing, this should be done immediately to prevent moisture
penetration. Wash and dry thoroughly before touching up. Use spray-on or brush-on rustproofing
compounds.
There are two different types of rustproofing compounds available:
a. thin (transparent) for visible parts.
b. thick, for parts on the underbody and wheel housing which experience most wear.
Parts of the car which may need to be touched up and the recommended rustproofing compound are:
visible welded seams and panel seams-(thin)
underbody and wheel housings-(thick)
door hinges-(thin)
hood hinges and locks-(thin).
After completion of all work on the vehicle, remove excess rustproofing compound with a cloth soaked
in kerosene.
The sheet metal surfaces of the engine compartment are protected by a transparent wax-based
rustproofing compound. The compound withstands normal washings without deterioration.
Mineral based solvents will, however, dissolve the compound, especially so if they contain emulsifiers.
In such cases the wax protection should be renewed.
