Supplied in a prime-coated GRV finish, the panel is intended for professional body repair and restoration before being prepared and painted to match the vehicle.


What This Product Does:
The door sill forms part of the lower side structure of the vehicle beneath the door opening.

Its functions include:

• Forming the lower outer section of the door aperture
• Providing the correct body contour along the side of the car
• Supporting accurate alignment with adjoining body panels
• Protecting internal sill structure from direct exposure
• Providing a finished exterior surface below the door
• Maintaining the correct wide-body profile
• Providing a sound replacement section during accident or corrosion repair

Correct sill geometry is important because the panel interfaces with the door opening, rear quarter area and adjoining side structure.

Symptoms Of Wear Or Failure:
A body sill does not wear in the same way as a mechanical component, but it can deteriorate through corrosion or physical damage.

Common signs that replacement may be required include:

• Visible rust
• Bubbling paint
• Perforation
• Deep corrosion
• Accident damage
• Crushed sill sections
• Incorrect jacking damage
• Large dents
• Creasing
• Split seams
• Distorted door aperture
• Poor panel alignment
• Previous poor-quality repairs
• Cracking filler
• Water entering the sill area
• Damaged mounting or joining edges

Minor cosmetic dents may sometimes be repairable without replacing the complete panel, but extensive damage can justify replacement.

Why Replacement Matters:
A badly damaged or corroded sill can compromise:

• Body-panel alignment
• Weather sealing around the door
• Exterior appearance
• Corrosion protection
• Correct fit of adjoining panels
• Quality of structural body repairs

Replacing a damaged outer sill allows the body repairer to restore the correct factory profile and provide fresh corrosion protection.

Where damage extends beyond the outer panel, the underlying sill structure must also be inspected and repaired.
