Hello all, I am new to the site and I would appreciate some help and advice please. I am making a cross/marker for an unmarked family grave that I located for an aunt of mine. I intend making this by laminating 5 layers cut from a sheet of 18mm WBP plywood. I am going to seal it with a propriety sealer/stain and finish it with a coat or two of Yacht Varnish. I was wanting to know if I should seal/stain each individual layer before I glue them together. Would this add to its water/moisture resistance? and would it affect the property of the adhesive? which I would also want some advice on. I don't expect this to rival the Taj Mahal but I do want it to last a few seasons at least. Thanking you all in advance, WW.
