The rear window of my Testarossa has the beginnings of a couple of small area bottom edge delaminations. All other windows are fine. These small areas go slightly “milky” if washed and then take a long time for this to disappear in my dehumidified garage. I have tried using a thin crack cure liquid that is used on boat windows, but it has no effect. Does anyone have any advice about trying reach and to seal the bottom edge/trough that the window sits in and what May work? I have seen this issue on the lower corners of windscreens on a number of older Ferraris where the screen bonding must leak. However, at least with the windscreen access is easy. Many thanks
