Ok, so I finally got around to installing my rear window. Of course I first had to remove my existing window. After removing the seats and back pad I could clearly see where the bottom of the window glass was not bonding to (what I thought was) butyl tape. As I started attacking the window, I was praising the PO for using silicon, more butyl tape on the top and on the sides of the window. I guess the PO was worried that the water would run up over the window and not leak from the bottom where the PO had not installed any additional silicon caulking or butyl tape.

So after hours coaxing the window finally was free. I started the task of cleaning the area so install my new “rear defroster” window! I also discovered how the rear window wiring harness goes from engine relay board to the inside of the car. But what surprised me the most was when I started removing the lower caulking and noticed it contain a wire. So I started researching and found that in the stock manuals that you use

Solbit TWS 8mm length 10’ 6” checkout the instructions

So does anyone know where you can get this?

It's 5/16" butyl tape, available at any autobody supply and some auto parts stores.

The Solbit TWS 8mm was the factory material; and probably factory only. I have a few factory replacement kits and it was more like the regular butyl material. The factory used a caulking with an electrical wire in it. The wire was hooked up to a power supply after the glass was in place, and the wire heated up the caulking to make a better bond. Not something a monkey in a glass shop could be expected to do safely.

...Bostik made that stuff, don't know if it is available...
however, Bostik 940FS for sealing, or if you want to bond, 70-04.
Check it out on-line.
I've used a cold install of butyl strip, however, the hot melt butyl is
closer to the Solbit TWS, using DC voltage to melt and seal/bond.
butyl strip can be prep'd using a heat gun, (used for heat shrink).
Hope this helps...Dave

This is kind of cool to find out! I just removed my rear window and there was a small wire in the butyl and I was wondering why?
