About 6 weeks or 2 months ago I re-glued the upper left and lower right corners of the back window, It had separated about 4 to 5 inches on both corners, Repair came out fine. Now the whole rest of the glass has separated from the top. The only places it's still attached is where I had re-glued it. I think I will try and remove the glass completely so I can thoroughly clean it and re-adhere the whole thing. Anyone have any bits of wisdom to offer?
