A quote from my shop who do a lot of high end cars and customs windows:

"We use a Sika product called Mach-60 to seal rubber to body and rubber to glass. these are used mainly to prevent water from entering car."

That Sika Mach-60 is basically rubber urethane adhesive. It's for the later style windshields (993-up) that do not use a preformed seal and are glued into the body, then decorative trim applied afterword. The stuff turns to pure rubber when cured. One of 3M's version like the Mach-6- stuff is called Windo-Weld.

We want to fill the void around the seal with a bedding and glazing compound. It's a non-hardening tacky goop that fills the void. The urethane stuff is not a problem, it's just unnecessary because it makes for extra work the next time the glass is removed and replaced

Of course my German neighbor had something to say: "You must do it like the Porsche factory says."

Which is?



So the argument would be that new materials offer a better solution to what they had then.

In the mean time, I am back to cleaning old window cement from the windshield and Targa window channel....

Maybe with benzine!

The current argument that people use is an assertion that the factory didn’t use ANY

I’ve asserted that while you can debate the modern glues, you should use a glazing compound at least

You document FINALLY supports that

Thank you thank you thank you
