Perished glass seals cause leaks, rust and fogged interiors. Learn the warning signs and what to look for in a replacement.
The windscreen and rear window rubbers do more than hold the glass — they keep water out of the scuttle and rear parcel shelf, two of the worst rust traps on any classic. When they harden and crack, water gets in behind the glass where you cannot see it until the rust bubbles appear.
The tell-tale signs
Look for cracking or a chalky, grey surface, gaps at the corners, damp carpet or parcel shelf after rain, and fogging that will not clear. If the chrome insert (locking strip) is loose or missing, water tracks straight in.
Choosing a replacement
Seals differ by whether they take a separate locking strip or chrome trim, so match yours exactly. Fitting glass into new rubber is a job many owners hand to a windscreen specialist — the rubber is inexpensive, but cracked glass is not. Fit fresh rubber whenever the glass is out for any reason.
