What are you preserving your floorboards with?

I used Hirsch's Miracle Paint about 3 years ago. It has held up well. It is expensive but a quart goes a long way.

Just taking a break from "RUST" toration.

Any recommendations on what to use on the interior floorboards to prevent rust? I have been using POR15 elsewhere.
I am also curious as to what you are using on the underside?
