Re: Butyl or urethane... AAARG!!!
Very good information, presented well and it still seems to be staying "civil", BUT, I have questions....
I strongly feel the factory stuff was neither Butyl tape NOR ureathane. I think the problem is, now there is no happy medium.
I redid my rear window with butyl tape back in the late 90s. Not sure if the glass had been out before, but it was definitely no ureathane. I'm glad it wasn't. With butyl or Thickol, you can "cut" it out (leaves a helluva gooey sticky mess, but you can salvage the glass). Ureathane dries HARD. TOUGH. It's in, and it's in. Yes, that's why they use it on modern cars for structural and safety requirements. At work, sometimes we've had some of our fleet needing glass replacement. That's fine and dandy if you're replacing the glass anyway and you need to "forceably" remove the glass,.,,but tell me this...if I have a numbers matching car and have the original back glass (which I do) and I have a professional shop UREATHANE it in, what recourse do I have if I ever need to pull that glass out again??? In one piece???
Are there chemicals to desolve ureathane that won't eat the car, the interior and everything else around? You sure as hell can't cut ureathane with a piano wire...
Not arguing, I just need some clarification. Seems to me modern cars are all or nothing, there's no saving the glass if it needs to come out. On a classic, you want to save the original glass and hoping it "never has to come out" isn't very realistic.
Is there an example out there where someone SUCCESSFULLY removed an original windshield or kept the replacement windshield IN ONE PIECE after it had been ureathaned in?
Sorry for the spelling mistakes, I'm tired. Again, I'm not arguing, I just have never had these questions answered.
