It was new. I'm probably going to end up removing the windshield and go with a new seal

You may want to soak it in a bucket of hot water to soften it. Squirt dishwasher detergent in the groove to make it slippery so it's easier to install. Remember, if it's an old windshield gasket, it will be stiff too.
