    I have a catamaran (fiberglass hull) I would like to touch up a bit in the bilge & locker areas. Would brushed on waxed gel coat be a good choice? Or overkill..? The areas a rarely ever wet but I still would like a durable coating. Not real concerned about a flawless finish.
    Much thanks

    I'd be worried here about the gelcoat not bonding perfectly and thus encouraging osmosis. If the surfaces aren't excessively rough, Interlux Bilgekote is a good choice for this; it's not the prettiest stuff (kind of a flat grey colour) but it's good at taking abuse, oil, fuel, bacteria, algae, etc.

    If you can get it clean of old oils any 2 part EPOXY would be good choice.

    Just be sure to scrub the epoxy surface down with detergent & water a couple of days after it hardens.

    Don't use flowcoat.
    A two-pack polyurethane or epoxy would be better.

    Gell Coat is absolutley fine.
    Ensure you mix in 2% Wax Solution proir to adding the catalyst
    Ensure you abrade the area you intend to cover with 80 grit, vacuum the dust/debris and then wash the area using acetone.
