    I want to start selling my bare cat hulls up to 40 ft .They are male moulded single skined grp polester hulls. All the hulls I have made so far have had a differant end use so it is pointless me fairing them. But to give them a weather coat and to make them look saleable I roll on a gellcoat finnish layer straight over the sanded last chopstrand layer . It looks textured and ok.
    I use polyester resin and q cell for a fairing compound can that be used over the gellcoated hulls ? Or am I doing it all wrong ?

    No, nothing wrong with gel and Q, it's one of my favorites, besides, when you use resin or gel as the base for the putty (I often mix them 50/50 for better strength (vinylester, that is)), it's the same material that's underneath.

    50/50 ?

    thank you yoke , do you mean 50% gel and 50% vinyl-ester ?
    p.s What is the correct term for a hull construction method that is a single lay up as opposed to a hull and deck set up?

    Eloc,

    Yes, precisely. Since I do a lot of repair-work, I have to do a fair bit of bonding to fully cured laminates, and the vinylester just gives a lot better bond-strength, so consequently, I use either VE or epoxy almost exclusively.

    As for your second question, I don't know, unibody maybe?

    Yoke.
