Well, in the 1960s and through the 70s, there were two sealers used for two purposes. There was a tar-like black compound that never really dried and was in a tube with a tapered end. You cut the end off to produce the size of bead you wanted just like today's caulk cylinder and squeezed it out like toothpaste. If it took you 20 minutes to get the windshield in there, you had no time pressure. Then there was a cap you screwed back on when you were finished. If you got this on your hands, mineral spirits or turpentine would remove it. Then there was a liquid that came in a red tin can a little wider in diameter than a soda pop can with a screw top. You poured this into what looked like an oil gun and applied it between the rubber and the glass when everything was in place but before you went back and added more of the tar-like sealer under the seal piece. The liquid dried fast and stuck the rubber to the glass. You had to follow yourself with a rag and be careful with that stuff because it would damage paint. The windshield I removed recently was still stuck fast to the rubber piece after 40 years. The end of the applicator was about 1/2 or 3/4" wide and maybe 1/32" thick. It looked like a duck's bill and slid between the glass and rubber. I guess that went by the wayside, but it was a pretty neat gizmo. Attached is a picture showing that stuff still on the glass. It was applied in 1979.
What non-hardening sealant would you use today? And what between the glass and rubber?
