The original intent of the wire was to cure the urethane and it looks like it can be reused. Old style urethane was very hard to cut, I use mig welding wire, vise grips and a battery charger set at 6V.

Newer urethane is soft, to cut it they use plastic string and a suction cup mounted winch. A cold knife works also. ( this is a 90* blade on a handle and a cable handle to allow you to pull )

When I changed the glass on my 97 C-280, most of the lower end was not sealed. The glass had been changed 2 x prior and they never cut the old urethane off the pinch weld. They just used a thin bead of new urethane. And, the clear coat on the pinch weld lost adhesion to the base coat so what was left of the urethane just pealed off. There were lots of scratches on the paint that had started to rust.

I posted this a while back and hope the link still works. ( I don't have a fast internet connection to test. )

The very British, Shakespearean actor reduced to narrating automotive training films.

The narrator is maintaining professionalism but really wanting to go off on a tirade about not getting good theater gigs any more.
