Mike from Conroe writes
Since Repels-All Liquid Concentrate contains natural oils and egg solids, we do not recommend that you spray this or any other natural repellents on finishes such as a car since it may damage the paint or other finishes. (It also has a very strong odor that you would smell when using the vehicle.) If you would like to tell us more about your application, then we may be able to recommend an alternate product or treatment for your needs.
