No, it was replaced before XX years ago by Carjoy.
I know that by replacing, they clean and paint the kit area.
The welder did a very good job and keeped the window in doing it.
If the windscreen is never replaced by your car the kit would be vey dry.
It starts leaking in the down corners.
If you look under the dash you can sometimes see light to the corners.
Most of the time the roof starts coming loose to.
That results in leaking from above corners windscreen.
The best thing to do is get the windscreen out and now you there fix the roof as well.
The windscreen has to be out to get the roof of.
Use watertight rivets if you do so and a PU kit.
Down corners rust.
It is unbelievable how easy the old kit comes of.
Sidewindow almost fall out by itself.
However if the windscreen is done before it wan't be so easy getting it of.
Here you see a pic of the roof.
It is glued in between the screen and the frame.
On the other hand, this car had some very slight bubbling in the corners.
I schatched it out a bit and put some Fertan in it.(rustconverter).
After that I put kit in between the glass and the frame all around closing the gap.
No more leaking and the frontscreen is locked in place.
This is done in 2008 and still OK
Hope this clears things for you.
