I've finished hardwood plywood with polyurathane, but that was really just to act more as a sealer for a storage cabinet in the garage.

Now I'm considering building a home-entertainment center. I'm not sure what wood will be, but I'm pretty sure I'll use plywood for a multitude of reasons.

What finishes can I use, and what finishes should I avoid?
Are there any books on the subject of finishing plywood.

Thanks,
Roger
