Haulout is coming up in a month. At 20 yrs old, re-bedding is on the list for portlights and rub rail. The lower rubrail is due, I've had some random screws that were loose, some rusting. Plan is to remove the stainless cap, drill & epoxy fill loose screw holes, then re-attach. New screws as needed. I'm debating whether to use butyl tape or 3m 4000 UV caulk on the rail. My concern is that the butyl may have a tendency to squeeze out well after install, creating a cleanup mess that's difficult once back in the water. I believe the butyl will be more resilient when the rubrail... rubs.
I'm not sure what I'll use on the portlights, I've not removed any, so I'm not sure what I'll find. But I'm leaning towards butyl on the exterior parts of those. They're manship portlights, they mount from the inside with a flange inside and another loose one that attaches on the outside. The forward ones are subject to sporadic submergence, so a good seal is important!
