Last October, I removed all the flooring. Split and remove bungs, remove screws, pull floor up in three major sections. Took them home and removed all the old finish with a heat gun. Palm sanded it with 200 grit. Now putting on coats of semi-gloss urethane. Gotta tell you, looks like a million bucks. I have a talented friend who was going to make me a new floor in oak with ash inlay, but the old floor has been resurrected. Can't wait 'til spring to install.
