I've been reading up on that type of water-based polymer, and it ought to
work. It should be probably available much cheaper from the actual
manufacturer (I haven't found who makes it), but one probably has to buy it
by the drum. For the small number of boards I make it isn't really cost
effective, so I'll stick to the pre-coated material.
