Using liquid glass to fix a blown head gasket is generally a temporary solution rather than a permanent fix. While it might provide a short-term seal and allow the car to run for a limited time, the longevity of the repair can vary widely depending on the severity of the damage and driving conditions. In some cases, it could last a few weeks to several months, but ultimately, a proper head gasket repair or replacement is recommended for long-term reliability. Regular monitoring of the engine's performance and coolant levels is essential in this scenario.

In HVAC systems, various types of gaskets can be used depending on the application, such as rubber, cork, or silicone gaskets. Commonly, rubber gaskets are favored for their flexibility and ability to create a tight seal against air and moisture. For high-temperature applications, silicone gaskets are often preferred due to their heat resistance. It's essential to choose the right gasket material based on the specific operating conditions and requirements of the system.
