Hey auto glass guys....

I just replaced the windshield gasket in my 56 Olds with one from steel rubber products and it worked great except in the bottom corners. The leaks are at the bottom corners of the gasket/glass. When I push on the gasket water squirts out from between the glass and gasket.
Is this just a new gasket that still needs to find its place or should I seal it up with some weather strip cement?

The spot is right above the area where the fender edge meets the door edge in the first photo.
