It a is paint like coating which is sprayed into the underbody, wheel well & etc to prevent rust. It comes with X years warranty (where x depends upon package you choose) and every year the coating is checked and resprayed if necessary.
However, its is optional and I don't recommend it because the rust usually doesn't occur to the area that is being treated under the package name "underbody coating". I mean nowadays all cars come with factory coated anti-rust coating or galvanized to the underbody metal so rust doesn't occur easily to it. Atleast not within 10 years.
But hinges, fenders, exhaust pipe, door bottoms, engine guard and etc (even if they are painted) are more exposed to rust so you should take care of these often. Read these guides: Link 1
