    Default Help please - Aluminum rivet sealing

    Please don't flame me - I know this is a WOOD boat forum - but - I have a friend that has a 75 year old sister that spends her summers on an island in Canada by herself! She gets there using an old aluminum boat which leaks around the rivets. Years ago my brother bought an aluminum boat that had the same issue, and I bought some liquid in a small bottle that sealed the rivets, Does anyone know what this product was called or what can be used to seal the rivets? Your help will be appreciated.

    It would have to be some sort of glue or sealant, fairly flexible after it has set. I suspect that epoxy might do the job, hard to say for sure. Gotta be some old fishermen hangin' around the harbor that 'ud know this one...

    I suggest West System G-flex two part epoxy. Easy 50/50 mix ratio, and the instructions tell you how to seal and repair both aluminium and various plastics. Worked well for me.

    I fear the G/Flex might be too viscous to penetrate the crevices around a rivet. I'll bet there's a Loctite sealant that's thin enough to penetrate and sets up sorta firm.

    There is at least one made for locking of pre-assembled (threaded) fasteners - 294

    I knew I'd seen something on this recently. Jamestown Distributer's has a bunch of "How To" articles. This is just the one you need.

    Aren't riveted-aluminum hulls built with some kind of mastic-sort of tape between the plates? If that's wearing out, dunno what you'd do, unless maybe that miracle liquid leak finder stuff that I've tried with little success.
    If the rivets are loose, it should be possible to dolly up one side with a three=pound hammer or a autobody worker's dolly, and hammer them tight with a deftly applied ballpeen.
    There's also some goo, from the makers of "Liquid Steel," called "liquid aluminum." This may even work, for all I know.

    The rivets and the boat might be shot, someone should have a good look at it for the old lady.

    The G-flex fix looks promising. Here's another possible angle: Airstream recommends a compound for this job on their trailers. I think it's an Alcoa product but I can't remember the name of it at the moment. It comes in a tube and is a very low viscosity silver liquid that penetrates, fills, and seals small gaps around rivets and joints between skin panels. I've got some at home and will dig it out this afternoon...

    FSS172 - I think that the Airstream fix would work - please forward the product name - thanks -
    I found some from Gander Mountain that looks like it will work too

    Liquid neoprene...comes in a tube or a small jar with a brush attached to the lid...use a cleaner and a toothbrush to clean the seam as best you can before applying. I think I got mine from one of the big catalog machine parts stores/outlets.....

    OK, the Airstream recommended stuff is Alcoa Aluminum Pigmented Gutterseal:



    It's a very low viscosity compound that gets drawn into small holes, crevices, seams, etc. I have used this successfully to deal with leaks on my trailer. I have no clue if it would work on a boat.

    Check out G /flex, I read an article recently that covered the very subject you are asking about, google G/flex and it will come up. They have a specific article that covers what you are wanting to know.
    There is nothing quite as permanent as a good temporary repair.

    A most interesting thread.

    I'm currently restoring a Court 6.5. Rivets r' Court.

    I'll remove 300+ rivets tomorrow and find a few bolts to work. Court WA were very cheap when they built boats. They built nice boats ... shame about the rivets.

    Bolts above the water line ... it is now.

    A most interesting thread. How do you stop a rivet from leaking? ... use the right rivet type and treat the interfaces correctly?

    I'm currently restoring a Court 6.5. Mega dosing-out on cheap rivets r' Court.

    I'll remove 200+ rivets tomorrow (from gunnels, tracks, beadings and bulkheads mostly). I'll find a few (hundred) bolts to work, instead.

    Court WA (from over in the Wild West, in Dingo's dell) built fine boat designs ... shame about the penny pinching aluminium rivets they excessively used for everything boatingly.

    It is fascinating seeing how cheap rivets leak, break, pull-out, distort, rip skin and make my day ... most riveting indeed.
