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
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.
Short answer, NO you do not NEED undercoating.
It will depend on how much undercoating you are wanting to rubberize.
No.
Do you know the expression, 'Don't tar everyone with the same brush'!
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.

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.
The best method for using tar to repair a roof is to first clean the area thoroughly, apply a primer if needed, then spread the tar evenly over the damaged area using a trowel or brush. Allow the tar to dry completely before applying a second coat if necessary.
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.
Kerosene works very well and will not harm the windshield. Brush it on and let sit for a minute, then wipe the tar off. Wash thoroughly with alcohol.
No, undercoating should last for years.
