Parts Desk Insights
Best Use Case: Best used for cleaning up and re-sealing above-the-waterline joints where mildew resistance and long-term flexibility matter (for example, head/galley-related seals).
Common Issues: For best results, remove old degraded caulk completely, clean and dry the surfaces before application, and use consistent bead placement to avoid gaps that can become moisture entry points.
