If I may digress with a good memory. My dad was a body man and in his day he swore by Dum Dum sealant on the older windshield designs . Google and search this forum. I suspect today's windshield installers have their preference that is probably more eco-friendly. People would come to the shop with leak problems. The leak always seemed to roll over the dash and down onto their nice shoes, pants or dress. He would dry windshield and rubber seal. He'd pinch off a bit Dum Dum, roll it out like a noodle, pull the rubber back and work it into the gap. The stuff stayed "sticky" and didn't harden. A quick and lasting fix. He'd wink at me and say this is easy money.
