On newer car they say its your choice but not generally needed. If you live in the north like say Michigan it would not hurt to do it. It may increase your cars value. In south like Florida, cars still rust but no where near like northern states. salt is the major thing that rusts out cars anymore. if you get a paint chip is where it typically starts, it needs to be fixed or it can rust or if you have a hole in the outside of your car for whatever reason. hope that assists.
