I have just finished glueing up the hatch stiffeners and the lip inside the rear deck on my CH16. What i need to know is what sort of gap do i need to have before i epoxy the edge of the hatch and the bare wood edge of the deck, at the moment the gap is under a 1/16th all the way round (basically the width of the hacksaw blade i used to cut the flush hatch out with)

Thanks
