WARNING! Windshield Gasket SHORTAGES!!!!!!!

Is it a bad idea to clean and reuse the old gaskets? I like the cost savings even if I have to use a little elbow grease but will it still seal? I need to find a new front and rear soon or go the re-use route.
i would not they are cheap + the mopars are known for leaks y do all that work for it to just leak just my 2 cents
