    I have couple to stainless steel snap hooks on my boat that are causing black stains on the gelcoat.
    What are these stains ? Are very hard to remove.

    Are non-steel snap hooks any good as replacement ?

    THANKS,
    V.

    Thanks!
    I'm considering replacing the hooks with Dyneema soft shackles: what drawbacks have these ?
