A rodent and insect repellent system that effectively deters or repels rodents, squirrels, small animals and crawling insects from entering vehicles such as cars, trucks, motor homes, trailers, tractors and recreational vehicles. The invention is a process in which an application of a non-drip oily coating is applied to the entire undercarriage and engine compartment of a vehicle. The coating prevents rodents, squirrels, small animals and crawling insects from traveling across areas coated. This coating stays we and slippery to the touch, yet it will not drip or dry out. In addition, the coating is scented with natural essential oils which overwhelm the acute sense of smell that rodents have and drive them away from the vehicle.
