if you can tell where the car got sprayed then go to the store and get you some V8 tomoato juice and put on the place where the skunk sprayed the car.
Do this in the shade on a cool car meaning cool body panels or underneith.
Let it sit for 10 minutes then squirt it off.
if you do this at home and its the under carrige then squirt it off then go to the car wash and squirt it off.
if its the body panels meaning paint then wash with your regular car wash soap you use.
