Mercedes glazing repair kit

[Damian]

I have recently perchased a glasing repair kit from Mercedes and it did not come with any instructions, woul any one know how to use it? The part number is 126 670 01 93.
I purchased this to put the glass window back into my hardtop on my w107, as it had come loose. The kit comes with a two part primer that looks like you mix and brush on as it came with a small brush, and a spiraly wound urathane looking tape.
I was expecting it to come with a tape containing two wires that you attatch to battery and heat up. This was the case with the old one and exactly how I removed it.
Mercedes could not give me any answers to this problem. They were willing to sell me the kit, but apparantly no one in there service department knows how to use it.
If anyone can shed some light on the situation I would be very gratefull.

Regards

Damian
