Make a test board is really good advice...
Steel wool, hand-rubbed, tung superiority, stain, thin for penetration, matte finishes, and other anachronisms die hard. But die they should.
My favorite "easy but good" finish starts with a small can of spar varnish and an equal volume of fresh, artist grade oil. Slop on a coat of plain varnish, let stand 10-15 minutes then rub dry with a lint-free rag. Let dry and repeat.
Refill the varnish container with the oil and add more coats. Refill the can with oil as you go. Stop when pores are filled and you are happy. Let it cure for a month or so before rubbing the finish out and waxing.
It will be very easy to repair the surface and the high varnish content in the beginning will produce a much better seal coat.
