All sealants have their proper and/or preferred uses, and silicone has a number of such on boats...usually where flexibility, removeability and thickness are important criteria. FWIW what comes to my memory are the OEM instructions for Beckson opening ports and replacement lens for several hatches ( see DIY-BOAT.COM - Hatch Lens Replacement 4/20/01
) which specified to use only silicone as sealants.
