Just a thought...was the silicon you chose specifically designed for windshields. You say the pinch weld was sound all around, huh. Of course in hindsight you probably didn't water test after 24 to 48 hrs. cure out. Interesting, I'll be dealing a windshield/gasket change out on my '59 in the near future. I don't think mine has ever been changed rubber hard as a rock. Good Luck....lets see what the experts come up with.
