Thanks,

That was a really interesting demo. Gotta love the attention to detail.

GM never used anything like that. It wouldn't pass federal safety specs.
They used pumpable Thiokol with a fabric dam to retain it.
Here's JohnZ's detailed description from: http://www.camaros.org/forum/index.p...37162#msg37162

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">GM never used butyl tape or anything like it to install windshields or backlites. Period.

The body opening flange was coated with black silane primer using a flow-brush 30 minutes prior to installing the glass, and all the reveal molding clips were installed to the Body Shop-installed weld studs.

The glass was placed on a powered rotating fixture, inside edge up, retained by suction cups.

The glass periphery was cleaned using a solvent, dried, and a different silane primer was applied.

A fabric-reinforced self-adhesive foam rubber &quot;dam&quot; was extruded and applied to the glass just inboard of where the Thiokol adhesive would later be applied; the purpose of the &quot;dam&quot; was to contain any Thiokol &quot;squeeze-out&quot; so it wouldn't show from the inside past the edges of the interior garnish moldings after the glass was installed to the body.

After dam application, pumpable Thiokol adhesive (with a pyramid-shaped cross-section created by the dispensing tip) was applied adjacent to the dam, all the way around the glass.

Lower glass supports were fixture-located and screwed to the cowl, and rubber spacer blocks were glued to the opening flange. The spacer blocks set the height of the glass relative to the body to ensure a good fit of the reveal moldings.

The prepared windshield was removed from the rotating fixture, installed in the body opening, and pressed down against the rubber spacer blocks; wooden tonque depressors were used to &quot;paddle&quot; the Thiokol around the edges at a 45* angle from the top edge of the glass to the bottom edge of the body opening to ensure a continuous seal all the way around the glass.

Reveal moldings were installed.

That was the plant production process, and explains what is sometimes described as a &quot;rope&quot; being found when an original windshield is removed - the &quot;rope&quot; is the fabric-reinforced rubber &quot;dam&quot; that was applied prior to applying the Thiokol adhesive.

If you'll look in Section 4 (&quot;Fixed Glass&quot in the Fisher Body Service Manual, you'll see exactly the same process for windshield replacement, except the &quot;dam&quot; wasn't included with the Service kit - masking tape was used instead to control &quot;squeeze-out&quot;.

The Thiokol installation passed the Federal MVSS windshield retention tests, and contributed substantially to the body's torsional stiffness; it also helped the structure pass the roof crush test. It's illegal to replace a windshield with butyl tape, although some glass shops do it as a less-expensive short-cut method instead of doing the job right.</div></div>

Thanks Kurt -- same procedure should apply to my 71' Nova ... TAZ

I just today installed my windshield like the video and it worked great. My car did have a rubber looking gasket or dam already in it. I doubt if the glass had ever been out

[firstgenaddict]

It's got a cloth strip to keep the installer factory from pulling the dam and elongating and deforming it thereby making it's profile and height thinner,

Cloth strip works like the STRING in the original trunk weatherstrips keeps from being stretched.
