The seal helps close the joint around the convertible top stowage box, providing a protective barrier between adjoining body and roof-storage components. Its purpose is to help prevent unwanted water, dirt and debris from entering areas that should remain protected while also maintaining the correct factory fit and finish around the convertible roof system.

With age, exposure to sunlight, repeated roof operation and changing temperatures, the original seal can harden, flatten, crack or become damaged. Replacing a deteriorated seal helps restore effective sealing and protects the surrounding convertible-top and body components.

What This Product Does:
The seal is positioned around the convertible top stowage box area and forms a flexible barrier between adjoining components.

Its main functions include:

  • Helping prevent water ingress
  • Reducing entry of dirt and debris
  • Sealing gaps around the roof stowage area
  • Helping protect surrounding trim and components
  • Supporting correct fit between adjoining panels
  • Reducing unwanted movement and potential rattles
  • Maintaining the vehicle's original factory-style finish

Because the convertible roof repeatedly opens and closes, seals in this area must remain flexible enough to conform correctly to the surrounding surfaces.

Symptoms Of Wear Or Failure:
Common signs that the convertible top stowage box seal may require replacement include:

  • Cracked rubber
  • Hardened or brittle material
  • Flattened or permanently compressed sections
  • Torn or split areas
  • Missing pieces
  • Seal pulling away from its mounting surface
  • Poor contact with adjoining panels
  • Visible gapsWater entering the roof stowage area
  • Dampness after rain or washing
  • Water staining around surrounding trim
  • Increased wind or road noise
  • Rattles from adjoining components
  • General deterioration due to age

A seal can also look relatively intact while having lost the flexibility required to form an effective barrier.

Why Replacement Matters:
Replacing a deteriorated convertible top stowage box seal helps restore the protective barrier around the roof-storage area.

A new seal can help:

  • Prevent unwanted water ingress
  • Keep dirt and debris away from protected areas
  • Restore correct sealing pressure
  • Protect surrounding trim
  • Reduce the possibility of moisture-related corrosion
  • Maintain correct panel contact
  • Reduce unwanted noise or rattles
  • Preserve the convertible roof system
  • Maintain the vehicle's original appearance and finish

Replacing a relatively simple seal can also help prevent more expensive moisture-related problems later.
