    I'm in the planning phase of building my first boat, a 12' rowboat. It's from very easy plans and I hope I don't have too much trouble.

    However, the plans that I have are kinda old and, when sealing the chines to the transom and such, instruct the use of twine and white lead. Twine I can get, but I'm pretty sure that they don't sell white lead anymore. I'm even more sure that I don't want to use it.

    So, what can I substitute for the white lead?

    Thanks,
    Terry

    Here are the plans if anyone needs to see them.

    Like I said, it's a very simple and easy design. I wanted to start with something fairly uncomplicated.

    Thanks,
    Terry

    Use polysulfide and you won't need the twine

    Gonzo's got it, use 3M 101 (polysulfide) and pack it into the seam tightly with a plastic applicator or putty knife. You can sand off excess when fully cured, but this can take a while depending on conditions. Hot and humid helps the cure. Hanging soaking wet towels over the area really helps.

    Exactly what I was looking for; thanks!

    Of course, at $30 a 10 oz tube, the sealant is likely to be the most expensive part of the project now, but, as I don't particularly want to have to dredge the boat out of lake Fort Phantom, I suppose the cost is worth it.

    Thanks Again,
    Terry
