I have a wicked big problem, there is chewing gum all over my black paint. I think it kicked up off my tire and is now all over my driver side fender and door. I did a search in the archives and found that peanut butter is good to take gum off paint. I am not sure how i should put the peanut butter on the car so my question is should i rub the peanut butter on the affected area or let it sit there for a while. I also have a clay bar would that work?
