Have fun, polyurethane that sucker till it shines, but don't bother
with wax after the poly- it doesn't need it, and you won't notice much
difference. Shellac benefits from a nice waxing afterwards- and if
you're refinishing something where you're moving computer parts around,
it may be a better choice. You can fix scratches in shellac by
applying another coat, but poly just gets wrecked.

I still don't know why the Wreck hates poly so much. Works good for
plenty of things, and doesn't really look bad.
