My rear targa window came with sealant from the factory.

My '84 had DumDum in the lower corners, no glue anywhere else. I think the FSM calls it Butyl Caulk.

I finally had time to look at the factory manuals. The official procedure for the windshield and rear windows calls for glue under the rubber on both sides of the molding. The factory recommended "special cement" so who knows what the original material was. It's probably listed somewhere...

Dum Dum should work well if you can't find out what 'special cement' is....I suspect something that remains elastic unlike a cement.

There are all sorts of windshield sealants, many of which stay flexible. I can't see this being a good use for dum-dum, although I use it in other areas.

Just wanted to post a followup. I replaced the windshield last fall without any glue or sealant. My 88 year old father and I wrestled that sucker into place. We used the string method described in several posts on this forum and after a couple of false starts, we got it in. Starting at the top center worked for us but the last few inches were tough. I was on top of the car leaning on the windshield while my Dad pulled the string. I also used a small block of wood and a rubber mallet to gently persuade the aluminum trim into place. That was a bit tricky. You've got to give it a good whack or two. Slow and steady wins that race.

I finally, after all these months, let the car sit in a rain storm on Saturday. As soon as the rain stopped, I ran out to check on my car (fingers crossed) and guess what - NO LEAKS. No sealants or glues and no leaks.

If I hadn't read on this site about tapping that aluminum trim into place to get the rubber where it needs to go, I probably would have used some type of sealant too. Thanks to the pelican that posted that trick - many, many thanks!!!!!!

I should also mention that it's so sweet to be able look through a nice clear windshield. The old one looked like it had been through a sandstorm. Having that nice new dash is pretty cool too.
