Hi, Tom. I have had good results with Parks Pro Finisher Oil Modified Polyurethane. I would suggest 3 coats for high wear areas. I believe that you can buy this at Lowe's. It will take at least a day to dry between coats and you will want to screen between coats.
Jay is exactly right about cleaning and runners. I got to start thinking about doing that some day. If you are like me, the Parks is a good choice.
