hey i just got a e36 convt about a week ago.
i decided to put the top down .. and after i day i put it back up but now i see fold lines

try using a window cleaner. Im not sure what its called but its made for plastic convertable windows and is supposed to return them to their clear state. If the line is still visible, Im not really sure how to take it out, but I remember when my dad had a z3 he used to put a towel on the back window to stop the crease from forming. Not too practical if you're going to be up and down a lot though.
