    I never have nor do I recall anyone ever saying they have. I think it would make it a real PITA to get back off without damaging it.

    As long as the oring is in good shape that should be fine

    Service manual depicts EPNOC grease AP #0 for the cone cavity, and "water resistant" grease (aka Yamaha grease A - marine) for the o-ring. Nothing regarding any type of sealant product.
