i need help taking out the rear window on the 89 crx and the rear windshield window thanks i am doing lexan myself, i will work on a process with them step by step. on the crx so if it turns out alright just let me know, but before i do go on myself i need some more information about putting lexan on myself on the crx. well what i had in mind was going to home depot to get some lexan and by cuttting them out of the shape of the old window and placing them in then using self drill screws ( big ones ) to hold them in should i seal them up as well ?
