What I need to understand is where is bonding material located that needs to be cut with the wire? The Ebay item seems to consist of the glass triangle surrounded by a plastic frame. It's obviously bonded into that frame making it into an integrated unit. So are you saying that the glass + frame is itself then bonded in place in the car and THAT needs the cutting wire to free it.? Anyway, whatever the outcome, I need a replacement, so I'll purchase the Ebay listed item. Just done that .... £28.50, sent! That's not too bad, Eh? I'll have a look at removing the rest of it, later. If it's obviously difficult, then I'll take your advice, Steve, and have it done professionally!Best to buy the eBay just and get a local glass fitter to remove your old one before refitting. It’s a pig of a job DIY and will be much easier for a professional with a cutting wire.
