    Three coats of a water based polyurethane. Stays clear, does not yellow. Varnish and oil based poly have a yellow cast and do yellow over time.

      Varish does not.... not like oil poly.. ALSO.... varnish expands and contracts whereas poly does not. So thru winter and summer, your poly coated board will Crack and peel and you will have to sand and recoat board, but the varnished board will still be sweet.

    I would paint with an exterior paint for decoration and then use the water based poly after the paint is completely dry.

    Paint and sealer should be for outside use. It will last longer and face less.

    Todd Serfass. I specifically stated water based poly and not oil based. Oil based poly and varnishes do have a yellow cast and will yellow over time. All finishes become solid and do not flex as you state.

    You may have heard varnish used as a generic term for any finish, but traditional varnish describes an older form of finish that contains alkyd resin, oil, and solvents. When applied to wooden surfaces indoors or out, varnish cures into a thin and glossy film with a faint yellow or amber tint, similar to the finish achieved with oil-based polyurethane.

    Despite its ability to serve as a wood sunblock, it’s not all sunny when it comes to varnish. If varnish is not applied correctly or dried completely, it can peel, crack, or form bubbles that leave wood more susceptible to environmental damage. For optimal results, apply varnish in several layers using a natural-bristle brush. Then, allow this traditionally slow-drying finish to sit for at least six hours under fair weather conditions to give your wood surfaces a photo finish!
