Anyone whose back window is falling out or getting along in years dont worry. The top half of my window came loose 2 months back and really paniced as though i needed to replace my top at $1500. I bought a product better than the factory adhesive. Called URETHANE by 3M and squezzed it around the gap and is as good as new. I went through a brushless car wash yesterday and the rest of the window got loose (all but the first fix) I had half the tube left and glued it up perfect. The good thing about this product is that is sets up in 10 minuits only need to prop from the inside with wood the area that sags. I bought here a Bennets auto and cost $27 for the tube. This stuff is unbelievable and is a great fix. Its a bit messy so need to use plastic gloves and tape off on and below the window to keep it only in the place you want glued.You all that have convertibles might buy a tube now as will be very handy when yours comes loose and it will eventually fall out. Great investment!!
