Without name calling, I followed a respected member, Brain Martin's (MARTINSR) advise.
I really apprecate your kind words. I have had a number of discussions on this subject with Raven1 (sorry I don't remember your real name) and he is right and only trying to protect you guys.
Listen, when I wrote that it was before much training I have including glass setting. So yes, urethane IS what should be used if you want it the best you can possibly do.
But we can split hairs here too. First off, we are driving a car that is MILES from "safe" by todays standards. Tell me about it, I see hits on modern cars where there isn't even so much as a hit of possiblilty of injury to the occupent. The car I drive every day, a 1959 Rambler, I would be HURT bad. So what would urethaning in the windows give me? Nothing that is what. Don't get me wrong, I am not making fun of the proper way to do it like I don't care about life or something. Quite the contrary I value life a LOT, I treasure every day I wake and look up at that beautiful sky. But I also REALLY enjoy driving that 59 Rambler and CHOSE not to drive a boring late model car, why, because life is too damn short.
If you are ever in an accident in a 1968 Chevelle where your butyl tape window comes out, you are SCREWED and that window coming out isn't going to make one hill of poop difference.
Now, this goes beyond what "glue" to use. How about prepairing the pinch weld for the window? If you havn't epoxy primed the pinch weld over BARE METAL (no bondo, no seam sealer, NOTHING) and then glued the window to that epoxy primer, you are going against all guidelines to mounting the glass anyway. If you are bonding your windshield to a basecoat clear coat paint, you might as well glue it in with Elmers. The strength of that bc/cc paint is about as good as a paper clip in relation to the urethane adhesive.
This is a personal decision just as driving that old death trap is. If you want it RIGHT, if you want it the best you possibly can do it. And I can certianly see why any of us would want that, you will epoxy prime over bare metal and then urethane that windshield in just as all the glass professionals say.
It is STILL the right thing to do be damned our personal opinion on what chances we are willing to take. But it is as simple as that, a choice.
I have the windshield in my Gran Sport on butyl, I did it myself and I made the choice that this was the best thing to do for ME. This was about 10 years ago now. If I were to do it today, I would probably set it in urethane.
It's like the epoxy primer before bondo debate, it will go on and on and on and on.
