    Default Caulk recommendations for sealing cockpit

    Potatoe 1.jpg
    Looking for some help in choosing a caulk for sealing the cockpit. Something pretty flexible and moderately UV resistant. Thanks!!

    The right angles of the seat, kinda hard to see but you can see the lighter lines at the right angles. The caulk there has become quite brittle and is leaking water.

    Boat life caulk, years down the road it will be easier to replace than 5200.

    What did you initially use?

    No idea what it is, my grandpa-in-law put it on when he built it in '06, says he doesn't remember. I've heard 5200 is pretty horrible to replace... trying to stay away from that.

    Epoxy filets , big ones.
    Has the boat recently been exposed to the sun?

    It's been in indoor storage for last four years or so. I took it out for a sail for a few hours, probably the most sun it's seen in a long time.

    Yea, she looks fresh for a 13 yo boat.
    And please do not take this wrong, but I can see several amateur things (I won't call them mistakes),and among them may be that the ply pieces were "caulked" rather than epoxy fileted from the git go.
    Retro fitting epoxy filets is not a small job, but it's not huge either, if you get a few of the correct tools. It's the proper, permanent repair. Not more tubes of goo.
    Be nice to finish your heirloom family boat proper !

    I suspect Wiz is spot on. I noticed the same.

    I agree. I only looked on my phone and thought they were epoxy fillets.

    He might want to use goo in a tube. It's easier to apply and it is not as sensitive to UV as epoxy. He doesn't have a strength issue that would call for epoxy. Plus he could have movement in the wood panels that will break the epoxy bond.

    Yes Navy, But as far as UV sensitivity goes, the plywood cockpit parts need to be coated with "paint". It would be a continuation of the amateurishness to leave them bright.

    Lol, well you didn't include that in your suggestions, and even though I would probably paint everything but a few accent pieces. That's a personal choice for him to make. BTW I found very high presentage of solids prevents UV damage. I have used tile grout as filler for outdoor grante sculptures and it holds up without color change or glue failure.

    Out of curiosity, what are some of the other amateurish things you see? It was my grandpa's first sailboat, so I'm sure it was a learning experience for him. I'm all for the epoxy fillets. Do you have any resources you can point me to for doing it right? Also, what kind of paint you recommend? The brightwork is pretty, but it's a pain to maintain. Thanks for your help!

    Off Center Harbor has a really well done series on working with epoxy featuring Russel Brown. Here is a link to the first one: https://www.offcenterharbor.com/vide...ion-filleting/

    OCH is a subscription site but well worth the money. For less than a quart of varnish you can have full access for a year. They even offer a free trial bunch of videos.

    Mostly, the squareness of the edges and corners. The "hardness" of them can be a bit dangerous, like smacking yerself on the companionway corners,and paint and varnish will be easier to apply and stick better if they are all radiused. This can be done with simple plane and sandpaper or a softpad sander/RO.

    If she is built with epoxy, coated with epoxy, I'd stick with an epoxy barriercoat,like Interlux 404/414.
    For topcoat I'd use a two part brushable LP, like Interlux Perfection.
    These are stinky modern chemical coatings,many prefer the ease and less toxicity of conventional /traditional one part paints,but modern coatings last longer and are tougher.
    Got some more photos of her, description?

    Lotta hard corners there...bashed up toes, elbows and knees in your future. Take Wiz's advice and soften things a little. Epoxy fillets is definitely the way to go.

    Being a trailer boat you'd be tempted to stay with the bright finish if you can keep her under cover. At least until it's no longer tenable. I'm using International 2 part paints on my boat at the moment and very happy. Easy for a rank amateur to get good results.
