I saw this on jalopnik and they were using it on a jeep.

This is shown as an under car spray. That will prevent rust from forming, and keeps dirt/grim from building up. Its also shown keeping brake dust from sticking to the wheels.

I don't have a local installer, and the manufacture Fluid Film says check with Honda before applying. ???

If you live in a state where they use salt and you drive this car in winter, then yes, I would spray it on the underbody.

I have the underbody of my 4Runner coated with fluid film. It creates a barrier between the metal and salt. A lot of people in the NE who use it claim that it is effective.
