What This Product Does

The windscreen rubber forms a weather barrier around the glass, helping to keep rain, draughts and dust outside the cabin. It is relevant when renewing deteriorated sealing rubber or undertaking glazing work during restoration.

Functions

• Seals the perimeter of the front glass against the body.
• Helps limit moisture entry around the windscreen opening.
• Closes gaps that can admit air and cause whistling.

Symptoms of Fault

• Rainwater tracks appearing around the glass or dashboard.
• Whistling from the screen perimeter while driving.
• Rubber that has become brittle, split or visibly contracted.
• Persistent cabin dampness or musty odours associated with leakage.

Why Replacement Matters

Ageing rubber can lose flexibility and pull away from sealing surfaces. Renewing a deteriorated windscreen seal helps address these gaps and reduce moisture reaching interior trim. Inspect the surrounding aperture as well: damaged surfaces or corrosion may need attention before new rubber is installed.

FAQs

Can rubber treatment restore an old seal?
A conditioner may offer temporary improvement, but it will not repair splits or reverse significant shrinkage.

What should be checked before fitting?
Confirm the body style and production details, compare the original seal and clean the contact surfaces. Avoid stretching the rubber during installation.

Does every water leak indicate seal failure?
No. Establish where moisture enters and inspect the aperture and adjoining components before replacing parts.
