Need Help, model a windsield

Looking for best way to remove windshield gl*** with out breaking it. I am going to chop the frame but want save the gl*** for a other car.

Thank you in advance, Jeff

 

Undo all of the screws holding the frame together on the bench. Then use a block of wood or plastic and strike it against the frame evenly all the way around until the corner pieces seperate frome the frame. If at sometime it was glued in with urethane or silicone or some **** cout it first with a razor blade to loosen it up. Done plenty like this as I used to do auto gl***. Theres some finess involved so be patient. If you break it flat laminated gl*** is pretty cheap.
