Looks good. Speaking for myself, I use marine ply for the countertop. If it's for a shelf in a cabinet or some such thing I sometimes use exterior ply - depends what I have in the scrap bin. I almost always use epoxy as i have seen contac cemented laminate lift after some years and the epoxy protects the wood as well. Does require some ingenuity to keep in place until set for big pieces though!
