hi, i had my new windshield and new rubber seal installed. it leaks real bad. i had it resealed and it didn't help. does someone know a secret on how to seal it. i took it all the way out the second time and cleaned the glass and seal. i called the place where i got the windshield from and they don't do old cars with that kind of seal. any help would be nice...frank...:bananaman L.T.N.G.
When I had my new windshield installed in the 4 door, the installer insisted in using black urethane sealer along with the rubber. He said it will insure no leaks as with a replacement like this, if the rubber doesn't seat perfectly, it will leak. If the channel isn't cleaned out completely, there can be gaps in the seal. Mine hasn't leaked at all and I brought a used gasket to use as I didn't have time to wait until a new one was shipped before state inspection. A lot of installers don't have experience with the older rubber gaskets as all they use now is urethane.
Another problem is todays windshields are alot thinner than they used to be. The gasket is made for the older stuff so the fit is not near as tight.
THE WINDSHIELD NEEDS TO BE SEALED WITH SILICONE BETWEEN THE GLASS AND THE RUBBER. STICK THE END OF THE CAULK TUBE UNDER THE RUBBER FROM OUTSIDE THE CAR AND LAY A BEAD. IT CLEANS UP EASILY AFTER IT DRIES ON THE WINDSHIELD WITH A RAZOR BLADE. GOOD LUCK!!
mavoholic is right ive been in the autoglass trade for 22 years so ive pretty much seen it all what you should do is get the new gasket... it has a thinner groove to accept the new winsheild better.. then seal it with either silicone or urethane (note).. never use silicone between paint and rubber only glass and rubber silicone is acidic and will eventually eat thru youre paint and destroy the pincheweld some people say marine silicone is ok to use as it is not acidic but i cannot verify that .....when doing an old car like that all i use is liquid butyl its thin and flows into the gasket nicely also easier to clean and wont harden up so if it ever has to be replaced again it wont cause any grief
Only problem is the gaskets are reproductions of the original so as far as I know, you cant get one with a thinner groove.
When I had the front and back glass replaced in my green '72 Grabber, the first installer used urethane and new gaskets and both windows leaked like crazy. I took it back and thier old car pro pulled all the freshly hardened urethane off and used the soft/never hardening type instead. (I'm assuming liquid butyl). Good and tight, now. With the way these cars flex, they really need the flowing capability of the liquid butyl seal. It may ooz onto your "A" pillars inside in time, but at least the water doesn't get in!
precision automotive makes a replacement rubber for the thinner windsheilds i went thru this with my 69 dodge charger the rubber they sent me fit my thinner glass perfectly
