I would recommend it for sure. Winter's in New England anyway are super harsh on Honda's. Get it undercoated. Wheel wells I wouldn't. Just maintain cleaning them. And get rid of the rubber inserts on the rear wheel wells if you haven't, those will rot your car faster than going for a rat rod look.did you get the undercarriage coated? and the inner wheel walls? just wondering because im in NY and im wondering if its going to be needed or seriously recommended because my future car will probably be my daily, until i can pick up another for cheap.
