Minor patch to plastic rear window?

[Kim Crosser]

I have a very small hole/crack at the top center of the flexible plastic rear window in my Boxster. Rather than putting in a new window (ka-ching!) I suspect I can put a drop of some sealant/glue on the spot to keep it from leaking water and/or getting worse.

Are there recommended sealant/glue products I should use?

I thought about using a super-glue, but am worried that the fumes may cause crazing of the plastic around the hole and make it look bad.

The hole is virtually invisible, but I do get the occasional drop of water running down the inside of the window when parked outside in the rain, or after washing.
