How to thoroughly waterproof a Macbook?

I am just now coming to know the hard limits of water destroying equipment. I don't know if it's realistic to be able to have my Macbook as a floatable rubber ducky in the bath in this day & age, but products like [Liquipel](http://www.liquipel.com/) and commercials of scuba divers using iPads have me curious. Is liquipel the best protection on the market? Are there other custom shops that could do anything to make a MacBook either resistant to liquid or even waterproof?
