I've mentioned this book here before, Finishing 101, and I really like my copy. I've used it quite a bit, and every time I haven't used it, I've had to go back and redo my finish.
I mention it here today because it's selling for $1, which is a price you aren't going to beat with a stick. No idea why, but I wouldn't pass it up if you have any questions about finishing at all.
Thanks for the info , Clay. Just checked it out, and the current price has been adjusted $13.75. Oh, well!
