I think it would increase the cost by at least ten fold. Someone would have to put each sheet on saw horses, prime them, wait for the primer to dry, put first coat on, put second coat on and then install. If the sheets needed to be cut, the cut edges would need the same labor and time intensive treatment. It would be VASTLY cheaper to just throw the bad sheets away!
