SECTION 2B
SHEET METAL

This section includes items of front end sheet metal that are attached by bolts, screws or clips and related
accessory components.
Anticorrosion materials have been applied to the interior surfaces of some metal panels to provide rust resistance.
W hen servicing these panels, areas on which this material has been disturbed, should be properly recoated with
service-type anticorrosion material.
