7/8" is REALLY a long way to go. I have done many urethane as well as "butyl tape" (the "Ribbon") type window setting and that is REALLY a lot to try to fill. I'm with Dave, I would build the body up there before I tried to fill it with anything.

One problem is, if you were to put a bed of urethane or butyl tape it would be visible from inside the car (or thru the windshield from the outside), talk about uuuuuggggglllllyyy.

Thicken that area up and smooth it off on the inside then put a normal bed of urethane or butyl.

There are foam "dams" that you can get to run around the pinch weld. After the window is set if anything is seen it is this foam dam.

A couple of things to remember, the urethane is VERY difficult to lay out looking good without a lot of talent and experiance. It will cure to hard, the glass in your late model car is held in with it and IS a structual componant of the body! The butyl tape will never harden and is actually sticky forever. So if it is exposed, until it gets a coat of dust on it (isn't that a nice picture) you will have anything that touches it sticking.

By the way, nice graffics.
