Windshiled leaking? #1332993 Fri Nov 08 2019 03:21 PM

My windshield had been leaking and it had the original windshield and gasket. I replaced both the windshield and gasket. When I pulled the old windshield the the metal lip was in great shape. No rust. I cleaned it up and gave it a fresh coat of pain. I then install the new windshield and one piece gasket without incident. It went very smoothly.

2 weeks later we get rain.

It is still leaking in the same corner. As recommended I even caulked around the the gasket by lifting the gasket away from the windshield, placing the nozzle of the tube of black silicon caulk in under the gasket and running it around the entire windshield. As I moved the nozzle around the windshield and the gasket close back onto the windshield as I moved forward a small amount of silicone squeezed out indicating to me I had the proper amount of caulk in place.

I repeated this process on the part of the gasket that engaged the lip. See the two photos.

Any idea how or why the windshield is leaking?

Just a thought...was the silicon you chose specifically designed for windshields. You say the pinch weld was sound all around, huh. Of course in hindsight you probably didn't water test after 24 to 48 hrs. cure out. Interesting, I'll be dealing a windshield/gasket change out on my '59 in the near future. I don't think mine has ever been changed rubber hard as a rock. Good Luck....lets see what the experts come up with.

The silicone was for indoor/outdoor use and list it sticks to all types of material. Wood, metal, pain, glass, rubber, etc.... This is the type of silicone you use for doors and windows around the house. It did not get wet for at least 5 days after sealing it.

Perhaps the windshield divider post? Maybe it “capillaried” down the lip to the corner?

My 54 also leaks .when the window was replaced it was done by a glass outfit .It leaked in the same spot yours is he came back and put some sealant around it and it was okay for a few years but now it is leaking again. I was at the glass shop and was told that they would have to take the window out and clean all the sealant off .Said it would be cheaper to get a new seal as it should seal without the sealant.The sealant was a urathane that is used to glue newer windshields to the vehicle.

"My 54 also leaks."

If you have to get a new seal, spend the extra $$ and get it from Steele Rubber Products.
1954/55st windshield gasket - "standard"
1955/55st windshield gasket - for use with SS trim inserts

The less common gasket (for use with SS inserts) is less expensive - go figure?

Urethane is the wrong type of sealant for your windshield. It calls for a sealant type which does not become hard.
You need a new glass guy, bless his heart. He should know that these windshields do require a sealant and which kind is called for.

Yes you are correct the guy who put the window in and sealed it is no longer in the glass business.The glass shop recommended new seal due to the time it would take to clean out the wrong sealant

You said you sealed between the glass and gasket, did you seal between cab and gasket? The picture looks like the bottom corner of the glass may be a trifle small, which is not unusual. We used to work a piece of screen spline into the groove to push the gasket out. This would probably be next to impossible at this point, depending on how well the silicone on the glass stuck. Originally the sealant used was a caulk that stayed soft for a long time (most was labelled "bedding and glazing"}. Several years ago the FMVSS was amended to require urethane be used to retain any stationary glass in a rollover. This is probably why the shop mentioned used it. Unfortunately, it can be next to impossible to remove the glass and save the gasket when this is done. I haven't been involved in the glass business for 4-5 years now, but a couple weeks ago I was able to find a tube of "bedding and glazing" made by a Canadian company at my local NAPA to use on my nephews Chevy II. Any silicone used for these purposes should be automotive type containing no acetic acid (the vinegar smell) to prevent metal corrosion. Silicones were used on school bus windshield installs since they needed to be able to be kicked out in an emergency. Hopefully some of this long winded post may be helpful to someone. John
