Added or modified parts
All vehicle parts (body, chassis, equipment, etc.) that are add-ons or subjected to modifications must be protected against oxidation
and corrosion.
Areas free of protection on ferrous materials are not accepted.
Tables 2.7 and 2.8 indicate the minimal treatment that modified or added components must receive when it is not possible to have
protection that is similar to that of original components. Different treatment is allowed if it ensures similar oxidation and corrosion
protection.
Do not used powder varnish directly after degreasing has been performed.
Lightweight alloy, copper and brass parts must be protected.
