Default windsheild misalignment

I have a 70 convertible c3 that my wife and i replaced the windshield using the Windo-Weld Round Ribbon Sealer that comes in a roll. It looks like one side dropped a bit after installation. Is there any way to raise one side about 1/8 of inch? I was thinking using piano wire to cut through it like i was going to remove the windshield and just reset it or heating it with a heat gun to soften it and push up on side. Any thoughts on this problem? I hate to break the windshield. Thanks, Bill

I'm thinking your idea could invite leaks. I would think the only correct answer is to remove it and start over.

Test the seal for leaks...if it is O.K., install the trim pieces and we won't tell anyone!

I did the same thing on my 67 GTO. I put my fingers under the low side and pushed it up while have my hand on the glass and pushing it up, I would lightly tap the glass in the up direction carefully. . You can also try a plastic pry bar under the low edge. It went up the where i needed it to go. Considering it's only 1/8 inch will the trim cover it.

I have used this "Windo-Weld Round Ribbon Sealer that comes in a roll" in a number of windshield installs with good results. There is supposed to be a couple of rubber blocks in the package the ribbon comes in or you can make some. Once you get the glass in the right spot, glue the rubber blocks to the windshield frame butted up to the lower edge of the glass and it should stay put.

Hope this helps.

I don't know if you've re-installed the trim or not but I was warned to hire someone experienced in the installation process in order to get the height of the glass where it needs to be to avoid problems in the trim installation.

If the trim fits, but it's drooped, it might leak. If not do what doorgunner says.

I would stay away from the piano wire and if you still have some of the WindowWeld stuff experiment with that a bit before you try anything on the windshield itself.

Hello,

"dropped" a bit?
Compressed the bead?
or
Slid down the face of the windshield frame?

If it slid down...are the 2 'stops' in place?

Regards...

The stops enable the glass to be in exactly the same place each time it's re-installed.
The stops are each held in place with a Philips washer head screw.

After "trying" on a half dozen old windshields, I have never been able to get the glass out without cracking it using guitar string wire. Usually it breaks across the bottom. NO problem if you are replacing the old glass, but if you want to reinstall, well too bad. A friend told me to remove and reinstall just pay a glass man to use his pro equipment. Hope this might help.

Hello,
The 'chancyness' with having a 'glassman' do the installation is that it could very well be his first one.
Understanding the need to do a dry-fit first so the SS trim will fit properly is difficult to explain to him.
It's SO easy to get the glass too close to the windshield frame or too far from it.
The 'kicker' is that in either case about the only thing that can be done is to start over.
Regards.....
