Parts Desk Insights

Best Use Case: Best suited for above-the-waterline sealing where you want mildew resistance and a flexible, non-yellowing silicone bondsuch as head and galley sealing jobs on marine surfaces.

Common Issues: For best results, keep surfaces clean and dry before application and confirm the sealant will be used on compatible materials (especially avoid oily contaminants). If youre resealing, remove old material fully and verify mating surfaces are ready for a proper bond.
