    New Question...... Have My Wooden Plug Built For 18' Skiff.....
    Have 2 Companies In My Area That Do Spray In Bed Liners For Pickups
    They Have Shown Me Examples Of Their Products Underside When Peeled Away (using A Release Agent).... Mirror Smooth--no Porosity Very Uniform--tough As Dirt..... And Fast (1 Hr Turn Around)

    Am Convinced This Would Make A Good Mold For Me To Laminate To Using Standard Methods Of Wax--gel Coat--etc......

    Am Clear On Bracing And Being Ridged. They Have Never Done A Boat Hull But See No Problems.........what's Your Thoughts Or Experience
    Anybody Tried It Or Know Of An Attempt?????????

    How would you attach bracing? What's going to stick to it....

    The mold will be made from the sprayed on truck liner ? Supported by what ? I know next to nuffink about this liner, but I suspect it is more flexible than would be useful for the job, but it will require support to some degree regardless.

    mold bracing.....

    Using the spray in bedliner......they make 6 to 8 passes (coats) to build the proper thickness.....it dries instantly.

    the bracing will be assembled and set to the side as a skeleton......

    on the third or forth coat the skeleton will be laid in place on the hull and now everything will be coated as one piece.

    after peeling the completed mold.....if there is flex..... a heavy mat could be layed up on the outside .

    If it works I could have say, 3 complete molds to work as multiples before
    lunch......

    I think that would have to be a pretty intricate skeleton frame to give it proper support. Maybe some bracing and then foam about 4 or 5 inches around the whole thing??
