I have a crack in my window that is too big for safelitte to fix. Is there something that I can do to temporarily or permanently repair the window until I am able to replace it.

    I infer that you mean the windshield. Is it on the drivers or passenger side? If they cannot fix it, I would doubt anything temporary would suffice.
I have heard of people using a sharp small drill to drill holes at both ends of a crack to keep it from spreading. I have no clue if that worked for anyone.
