Windshield gasket replacement $$$$$ ?

If the goal is to stop a water leak, get under there and confirm the water leak is in fact the glass/gasket seal. Wiper pivots leak, vent box to cowl seals leak, etc..
It's my belief that the rubber only supports and seperates the glass from the metal. The sealant used does the sealing. If I properly clean the rubber for reuse my money is better spent on a new glass. Good luck eith it
