Add me to the list of folks fighting with the roadster rear window. The OEM application really sux.

Anyway, using the 3M Window Weld with some success. We'll see. But we have to keep in mind that the Window Weld is a product intended to be used on windshield replacement, not necessarily intended for ragtop rear windows. With windshields, the stuff works fine, I'm sure. But when trying to glue a rear window, GRAVITY IS AGAINST US.

Just have to do the best we can. The problem I have with the 3M is keeping the bead of glue even so that no lumps appear. Been using strips of plywood and clamps to set the window and fabric together. Seems like a never ending battle ... short of a new top.
