IMO, Restore a Finish is more of a bandaid for antique stores to flip furniture. It's not a long term quality solution. Refinishing with shellac is authentic, or if you go to a Woodcraft store or online, (or other places) you can find old style varnishes that aren't polyurethane. (Poly is hard, but hard to remove also). Clear lacquer is also another option, harder than shellac, and a little more resistant to water and alcohol rings, but still easy to remove. Any waxes, will have to be removed before any other finish is applied. Glenn or Rodney, probably knows more about this stuff than I do, I refer to an OLD book I have, "The Furniture Doctor" which gives great info on all of the old refinishing arts.
