Windshield sealant is a silicone glass sealer that flows into hidden cracks and areas that may be harder to reach. The sealant provides a tough, waterproof, durable, and clear seal that will prove to be resistant to different types of weather conditions, extreme temperatures, vibrations and shocks, and even most chemicals.
To test if you have a leak in your windshield you can do a water check with a spray bottle. Lightly spray the water and let it flow over the edge of the glass. If you have just replaced the windshield and the adhesive has not yet fully dried, then avoid getting water mixed into the adhesive. If you find an area where the water is leaking through, then apply more sealant to ensure that this no longer happens.
If you are looking for a window gasket rather than sealant, we have an article with some recommendations.
