Butyl Tape Replacement

Hey All! I was wondering if anybody out there has found a better way to mount a windshield other than using butyl tape for my 65 Wagon? I am looking for advice or maybe there is a thread buried in here somewhere but I am all ears.

Thanks


Steve

Re: Butyl Tape Replacement

I had a local windshield shop install mine in my 69 el Camino. They used the black urethane in a cocking gun. They told me its the only way this should be done because the windshield is part of the overall structure in these cars.. Best $150 I ever spent! I would of had that stuff all over the place!! LOL....

Urethane is a much stronger bond than butyl, but they are incorrect when they say the windshield is a structural piece of the car. That is true on most newer vehicles, but not on Chevelles or most classics.

Black urethane on my 70 EC front and rear windshields. No complaints.

When restoring my first '67, the butyl was so brittle I was able to basically push the windshield out with just my hands. Odd because it was a very low mile car, but the glass had absolutely no effect on the structural integrity of the roof.

Re: Butyl Tape Replacement

I wished I would of just had Jeffs Auto Glass install a new windshield. The old glass ended up having scratches and is fogging. Had I driven the car with the old glass I would of known. If your not sure, its best to just buy new glass since the price isn't that much..

Re: Butyl Tape Replacement

Iíve seen several applications using the urethane on our classics. Many had embarrassing protrusion of the urethane past the reveal molding. Before I would let a glass installer set the WS with urethane, I would pre set the glass myself and mark the where the urethane should not be seen. I would order a dam rubber strip to install, keeping the urethane from squeezing out.

Re: Butyl Tape Replacement

The butyl tape was meant to space the glass the right distance from the window bed.
The last time I reseated the glass on my Impala I used the tape and a black tar-like
sealer to fill the gaps between the tape and the sheet metal. If the glass is too close
to the metal frame the clip-on window trim won't fit right.

Re: Butyl Tape Replacement

I appreciate all of you! I will pursue the glass shop option as this is going to be my third windshield and I am tired of leaks. The butyl tape was so hard to work with! Again, THANKS!

Re: Butyl Tape Replacement

I went ahead with most all of your suggestions and had a local guy install the windshield using urethane and I am very happy! Again, Thanks to you all. Love this website!
