"Am guessing it is the Waterlox Original Satin Finish."

That's it, Tim.

If you want to try it, I'd recommend you buy a quart of it and also a can of Dust Off or some other aerosol dust cleaner. When you open the can, remove enough to fill a small, 2-3 ounce bottle. As you replace the lid, blow the inert gas into the can constantly as you lower the lid. If you want to be really thorough about it, do the whole operation inside a plastic bag. Any of the tung- or linseed oil-based finishes will set up in the can if there's air in it. No big deal if you're working out of a 2 ounce bottle, but a quart is a lot to lose.

Don't know what your woodworking experience is, but even if it's considerable I'd recommend you check out these essays. These are a couple that cover stock finishing very well and I happen to agree with all their advice...

Winter is the time to tackle them. I'm not in a particularly humid area but, even so, the oils start giving me trouble about late March. I try to complete my finishing jobs Dec-Feb, then start on the checkering. Good luck and you can PM me with any specific questions.
