    Compatibility depends on the chemistry of both the sealant and the substrate. Always follow manufacturer recommendations and perform adhesion testing.

    Service life varies by product type, exposure, and movement in the detail area, but most commercial-grade sealants last 5–15 years when properly installed.

    Most sealants require dry, clean surfaces and specific temperature ranges. Application conditions should always follow manufacturer guidelines.
