Thanks, guys!
Brett, yes, I'm applying it inside. I've got about 4 coats on it. But my coats are really thin; Just enough to barely moisten the top and do a decent amount of rubbing in (which actually rubs most of it off). I normally apply like this on smaller stuff, because it gives so much control in the build, and allows a patient noob like me to get a good finish. I put down a coat b4 work, one when I return, and one before I sleep. Done this way, you never have to sand.
It's a lot of work on something like this though.
I've had luck with Waterlox (talking about the original sealer here) brushing it on thick, wiping it on slick, wetsanding it in, and 'polishing' with it. It just seems to like being applied any way. Just keep in mind: the thicker you put it on, the less you should fuss with it once it's on.
