The Anti-Corrosion Limited Warranty (Outer Panels)
Covers your vehicle for 5 years or 100,000 miles

To be specific, "outer panel" concerns the outer-body sheet metal panel—one that is finish-painted and can be seen when walking around the truck.

This warranty covers the cost of all parts and labor needed to repair or replace any sheet metal panels that get holes from rust or other corrosion.
