No.
Short answer, NO you do not NEED undercoating.
you can if you want to but i would not susgest it because then you will have problems under the car and no one will touch it
The undercoating color is determined by the manufacturer's choice and may not always be related to the exterior color of the car. The goal of the undercoating is typically to provide corrosion protection and sound insulation, rather than to be inconspicuous. Dark undercoating can sometimes provide a visual contrast to make it easier to inspect for any damage or corrosion.
It will depend on how much undercoating you are wanting to rubberize.
Undercoating is a waterproof coating applied to cars' undersides to prevent them from rusting. The parts under your car are also vulnerable to damage from the elements (especially in north climates), oil, tar, and items that fly up from the road.

Absolutely, positively not. The manufacture dips your entire car in a electrophoretic bath about 5 or 6 times to coat every nook and cranny. It is then baked in a dust free sun room. All the protection your car will need it gets when it is built. All you are doing by adding undercoating is adding about 50 pounds of tar-based gunk to the underside of your car. That gunk will trap dirt and moisture. Don't fall for the undercoating myth.
Under painting, or undercoating, is a coating added under the vehicle. It helps keep the underside of a car from rusting, and is especially helpful in snow or beach areas.
according to the info i read on the back of my can of undercoating, it only takes 10 minutes. I'd give it a 1/2 hr myself.

Car undercoating in Edmonton protects vehicles by creating a sealed barrier between the metal undercarriage and corrosive road salt used during Alberta winters. Road salt accelerates oxidation when combined with moisture and freezing temperatures. A professionally applied undercoating—either oil-based or rubberized—prevents saltwater from reaching exposed metal surfaces such as frame rails, brake lines, and suspension components. For Edmonton drivers facing heavy winter road treatment, annual undercoating significantly reduces rust formation, extends vehicle lifespan, and helps maintain resale value.
No, undercoating should last for years.
