Windshield Installation / 3M Window Weld
Has anyone used the following 3m product when installing the front windshield?
3M Window-Weld Super Fast Urethane (Caulking Tube)
Item Number: 8609
Are there any pro's or cons to using the 3M 8609 product? This is what the guy who has my car wants to use to install the windshield.
I was going to use the following 3M products
3M 08509 Bedding / Glazing compound between the rubber and the car
3M 08633 between the rubber and the glass
I ask him if he uses a rope to install the rubber gasket when installing the window, he stated that the rope is not required when installing a new window with new clips. Is this true??
What is the purpose of the using a piece of string/rope.
Thanks

If he says roping is not necessary I would recommend another person to install your windshield. As for the window weld last time I ordered it there was no problems but I too think it was 08609.... Works great though you just need the gun for it...

I use it, and I like it. It's pretty messy, but there really isn't anything out there that will work any better. I agree with Hitch, if you're installer doesn't plan to use rope, then he probably doesn't know what he is doing. If he doesn't use the gasket, and plans to "set" the glass, then the stainless trim won't fit.

I know you have a lot more knowledge than I but you have me thinking on this one. I am curious as to how one "sets" the windshield in a midyear without the gasket. The outer dimension of the windshield is smaller than the inner dimension of the windshield frame. The "H" channel windshield gasket supports the windshield and fills the gap. Or is there a windshield manufactured that is of a different dimension than the standard piece?

Rich,
You're right........it can't be done. The glass is smaller than the opening. I hadn't thought about that until your comment. The rubber is what holds the glass in place, so short of using it, I don't really know what his installer is going to do. Good catch.

Run away very fast from any Glass shop that wants to use the modern urethane sealant on your windshield, or face the consequences if you ever have to get those moldings off again in the future.

3M 8609 is a urethane, BUT it's ok to use it as a sealer for the rubber gasket. I think that what Dan meant was, don't let some moron stick your trim down with it, or you'll be buying all new the next time you try do get it out. Urethane stays flexible, and has very good adhesion, but it has to be cut out. Find a reputable shop that knows how to do a Corvette windshield, and they will know exactly what to do. There are also several good threads on this subject in this forum. Good luck.

OK one thing on the C 2 windshield. You can do everything you want to seal the windshield and will still have leaks. Its not the windshield leaking its the clip attachment hardware. Make sure you the sticky stuff to seal around the clip attacment hardware, went through 3 new windshield seals only to discover the white struuf did serve a purpose.
