Corrosion protection measures
To ensure compliance with the anti-corrosion warranty
of the vehicle manufacturer, upfitters must observe
important corrosion protection measures after drilling
through the body.
Whenever an assembly hole is made in the vehicle
body, one or more elements of the existing protection
system is/are irreparably damaged.
The upfitter making the modification is therefore
obliged to restore the quality of the corrosion protec-
tion system to that of the basic vehicle.
1. Protect the exposed panel edge
•
Remove drilling shavings.
•
Deburr the hole
•
Prepare the surface: Degrease the edge of the
panel and adjacent areas for painting
•
Prime and paint all unprotected parts (phos-
phate-containing base coat).
2. Ensure the leaktightness of the drilled hole, if it is
exposed to the outside
•
Use round bodywork sealing cord between the
installed parts and the body (except roof ventilation
elements)
•
Use silicone for the floor ventilation element
•
Spray underfloor protection on all attaching parts
which project downward out of the vehicle.
