Ordered 5 x 12mm sheets of marine ply, 4 perfect and one had unsightly repairs in outer ply, wood diagonals rather than filler so could have been worse. All sheet where flat and well made with no voids or areas of delamination. Despite it raining all day all sheets where delivered dry, had emergency and had to leave just as delivery was made. Driver was brilliant, unloaded by himself and covered ply sheets with plastic etc. When returning home later all sheets were perfect and dry despite heavy rain, so many many thanks for that greatly appreciated. Thanks David Baker
