    I broke my windshield 5 years ago when disassembling my car prior to restoration . No big deal , as who wants to squint through a pitted and scratched 50 year old windshield?
    Last thing to do before I can finally put some miles on the car, so I have a guy coming with a PPG windshield to install at my place.
    My QUESTION is this:
    Is the exterior surface of the glass supposed to be flush with the painted surfaces of the roof and a-pillars?
    Pictures prior to molding installation would be Grrreaat! ( read like Tony the Tiger)
    Thanks, Jim/Rott

    I believe the above, and btw, thank you for your reply, is speaking of the distance between the glass edge and the pinchweld. In other words the distance the glass is pushed up towards the roof edge. Also where to set glass stops on the lower windshield. I could be wrong. I suppose I could pop the metal clips and figure out the height of the glass by installing the molding without the glass in place. I am probably making too much of it. Jim

    If its not to late be sure to use the buytle tape to seal the glass and NOT the urethane goo. They will tell you its law that they use the goo and on new cars where the glass is a structural support that makes good sense. In our cars the sealer ribbon that it came from the factory is the way to go.

    Briz, Why do you like the tape over the goo? I had mine done recently with the goo and am very happy overall. The experience of the installer seems paramount.

    I bought one and it was perfect. If you are patient you can have it shipped with their regular shipments for $50. Otherwise $150. Took the cheap way and it was about two weeks.

    The glass settles down into the goo and it makes way to big of a gap in the moldings. New cars dont have window trim like ours do. Also if you ever need to pull it out you will break it before cutting through that stuff. Lastly when it does squeeze out and hardens you will need to cut it away to install the inner and outer trim. First hand exp.

    I had to fight with one installer to use the butyl tape on a past resto. Just picked up my glass from having the ribbon put on it. Repro dated windshield, original back glass which actually still had some of the old ribbon on it.

    I had to argue with the guy too. He finally agreed on the terms that it was ok only if it was a show car and not daily driven. ya right! Told him he could take his glass and leave if he was not going to do it as I wanted it. I've done it alone before
    its not hard but is easier with 2 people

    I called JNPhillips glass because they are a PPG distributor. They had the windshield, but refused to install it with butyl , stating saftey reasons. Jim

    mrolds69 "The Cure" Briz says, the tape is better. It's a lost art, like convertible top installation. Originally, they used spacers and from the factory they had foam dams they used so everything would be neat from the inside. The other factor is the thickness of modern glass, it's not as thick as the original. It's hard to find a good, old car glass guy who can set it at the right height.

    Right, did your car come with PPG glass? All Flint cars were LOF. Libby Owens Ford. Yes Ford Motor Company in our Buickā€™s!

    Cheers guys, to get the right depth on your windshield for the trim you need to use 3/8 buytl tape 3m part number 08622 3m calls it window weld ribbon sealer. 3m makes a primer for the pinch weld 08861 it's a 4 oz. can.If you want once the windshield is in the car you can put some urethane sealer around the glass then install your trim. It's easier to put the moulding clips on before the windshield is installed an don't forget the 2 clips that support the windshield along the bottom (see picture) hope this helps. Tim

    I used butyl tape on rear window and it was fine. I had a "professional" come out and put in new windshield. What a disaster.. He laid a huge bead of urethane in frame, neglected to use any blocks or spacers.. Urethane squeezed out and was visible from outside the car. Looked terrible. It wasn't till later I discovered it leaked like a seive. The urethane skimmed before the windshield was placed and never adhered to glass
