Tru-Oil is fine---Satin polyurethane is fine, also. It is important to fill the grain of the wood before proceeding to final finish. )ne thing I learned years ago..... after you get the old finish removed,and before you start putting on the new, sand with 320 and then place the sanded stock under hot running water and let dry. This will bring up the "whiskers" in the wood. Sand them off, and repeat this until no more appear. You can now start the finishing process. As for a good satin finish, I like to use an automotive rubbing compound after the last coat is THOROUGHLY dry, followed by a good paste wax. Touch-up from light scratches is easy with a small amount of Tru-Oil. Good luck...................
