Window gasket sealant..
Speaking of leaks,
I have a window that has what looks like the same type of black rubber gasket as found in automotive windshield applications.
The black gasket was originally a straight piece and they fitted it in the oblong opening for the window.
So that means there is a cut where the gasket start/stopping point is. That is where I noticed a small leak.
Any suggestions of some magic goop type stuff?
