I am replacing the windshield in a cuda and have the 3m windo-weld urethane adhesive 08609. i have read the directions and it looks like i dont need to use primer on the car body since it is all new paint and no bare metal but what about the glass? the directions say clean and prime the glass? i dont remember using primer last time i did a windshield and it didnt leak but that was a long time ago so i'm not sure.
another question , how wide of a bead of sealer do you normally use around the window before you set the glass in?
just looking for some pointers and advice before i go make a mess.

thanks
