Landcruiser Windscreen surround rust.

Has anyone has any trouble with their Landcruiser series 80 rusting along
the top of the windscreen rubber surround where the rubber meets the
bodywork.

I would be most grateful of any information.

That can be a sign of a bad primer application when a replacement
windshield is installed. The tool used to remove the damaged windshield
usually scrapes paint off the opening edge. The installer is supposed to
spray primer (usually zinc based one) on the bare metal before
reinstallation. To repair it you will probably have to remove the
windshield, repair the paint damage, and then reinstall the windshield.

Is this the usual occurance for the tooling to scrape off paint. The company
which did the new windscreen it appears has not used any sort of installer
or primer on the paintwork.

It is not that uncommon for the installer to scrape the paint a little when
removing the old windshield. Besides the gasket, I believe there are clips
to hold the windshield in place.

It is normal for a tool to be used and for it to scrape off paint in the
process...usually. It is almost unavoidable. That is why the installer
should and normally does prime the area before the new installation.

So anyone who fails to treat the bare metal basically has not done a proper
job. What could happen if the windscreen surround is left as it is.

It will eventually rust out and leak. If bad enough, it can compromise
the structural integrity of the roof and post system to affect rollover
protection.

Ultimately the whole body will reduce to iron oxide. Any Toyota or Datsun
sold here [UK] during the early 1970's had fist sized rust holes in the
bodies by the time they were four years old. This particular vehicle is
getting towards 15 years old already and will probably last until 20 years
old with corrective treatment. The sooner the better though.
This account has made me wonder whether the fitters who recently replaced my
100's screen sprayed primer on the metal. I suspect that since the weather
was freezing and windy when they did the job, that they did not. Time will
tell.
