Thought I would share what I found at Home Depot today, since animals chewing on cars in CO is a big problem.
I have a huge rabbit problem at my house, and they've chewed on my car. I went to home depot to look for moth balls, and found this instead. It smells like shit but supposedly when it dries, the smell isn't noticeable to humans. I sprayed it all over the front part of my house. We'll see how it works.
Home depot also had repellent for every other kind of animal too.
