So do you have to be dead on perfect the moment you set the glass, or can minute adjustments be made once it's down?

It takes 48 hours to cure. You have 5 to 10 min before you can't adjust window anymore. Side note. Urathan will stain anything it touches even your skin. So be very careful and don't use more than you need to.

What durometer does this stuff cure to?

Hi Travis! Thank you for your question. The 3M 08609 Window-Weld Super Fast Urethane has a 55-60 Hardness (Shore A).

Will 3m 08693 auto glass urethane secure the rear glass to a canvas convertible top? sides and bottom have separated and need to be glued.

Yes. I purchased a small piece of convertible roof fabric on ebay which matched my convertible's black top and I cut it to fit the lower part below therear window with about a one inch overlap onto the window. I followed the adhesive directions and glued the new material right onto the window andthe old convertible fabric. I let it sit for 48 hours. Today, you can hardly notice it was repaired and the adhesive still adheres to the glass.
