Oh no! Most customers have used our magnets on the back of their car, and I believe it would also generally work on the side, however I don't believe that these magnets are simply strong enough to handle the force of wind going along the hood of a car. We can work with you to get another one if you would like it for another spot on the car, or we might be able to make you a decal this size if you really want it on your hood and don't want it to blow off. Our customer service team will be reaching out to see what we can do for you.
