67 to 68 Windshield Installation??

Put the gasket into the car first using sealer. The bottom edge fits over the tabs and is glued to the car body along the bottom edge. Sealer is put in the channel along the outer edge of the gasket to seal it to the body. 3M makes a glass lubricant in a spray can that we used and it helps a bunch. The guy who installed our glass also had a couple of suction cup holders that allowed maintaining control of the glass the whole time. Make sure the gasket is not "locked" together before trying to put in the glass. Use a couple of plastic installlation tools (like a plastic putty knife with rounded corners) to work the glass into place. You can then run a little bead of sealer under the front lip of the gasket all the way around the windshield. Lock the gasket into place to put pressure on the windhield and let dry for a a couple of hours, and then check for leaks. If no leaks have fun with the trim. the two lower corners and where the tabs fold up are the main points that will tend to leak. We actually used a gasket and trim adhesive just along the bottom (but not in the corners) to insure that there would be no movement there in the future. With the rest of the gasket installed with butyl sealer you get the give that is needed and still maintain a seal.
