Is it a problem if it rains after replacing car glass?

If it's only short-term rain, it won't have any effect on the windshield. However, if there's prolonged heavy precipitation, the glass adhesive that hasn't fully dried might cause bonding issues. Additional details are as follows: Precautions: After replacing the windshield, try to keep the vehicle speed below 80 km/h for 48 hours, avoid bumpy roads, sudden braking, and car washing. Do not place sharp or thin items like parking permits between the dashboard and the glass or other adhesive areas. The fixing tape can be removed after 24 hours. Further details: If the rear windshield is replaced, avoid driving with windows open at high speeds for 12 hours to prevent wind resistance from affecting the bonding. Additionally, do not use the rear windshield heating function for 12 hours after replacement.
Last time I had my windshield replaced, it started raining right after the job was done. I was quite nervous at the time. I asked the mechanic, and he said the newly applied adhesive needs some time to fully cure, usually at least 12-24 hours. If rain hits it too soon, the water might wash away the uncured adhesive, leading to poor sealing that could cause future leaks into the car or potential windshield loosening. Fortunately, the rain wasn't heavy that day—I quickly covered the car with a protective cover and checked the edges, finding no water traces. After observing for a few days, everything seemed fine. To avoid such situations, it's best to check the weather forecast before replacing the windshield or park the car in a garage or sheltered area until the adhesive dries completely. After all, windshield repairs are quite expensive, and prevention is better than rework.
