Varnish?
Steve,I used a plain old oil finish (not even hyper-inflated boat store type). Watkins Oil is a good choice. It's cheap, durable, looks great, dries fast, and is easily re-touched. Varnish is OK, but prone to running. Also, it's kind of a permanent commitment. Once you do it, you have to completely remove the varnish (only sanding will take it off) from the entire piece to touch it up after a scratch, gouge, dent, or plain old peeling due to age. New varnish looks great; old varnish looks horrible. I can oil the entire interior of my 23 in 2 hours, and you won't cry if you spill a little.
