63 SS Nova windshield problems?
 

Had a severely pitted & scratched windshield that was leaking in my dad's 63 Nova. We got a new gasket from A&M Sofseal & put a new windshield in it. It is still leaking. Looks like water is coming between the window & the gasket. The body is perfect, no rust or anything so we know it isn't that. anybody else know what we can do?

Maybe ad some butyl between the two?
