I have used the poly oil finish for a table and it is remarkably durable. Would this work well to seal cherry boards for a bathroom ceiling?

    Shellac is a very good vapor barrier. Several coats would offer quite a bit of resistance. Then you can apply a couple coats of oil-based poly to add to the vapor resistance and to supply a surface receptive to cleaning.
