This spray is one of the few that really helps on the market. For some time, a raccoon who loves our car and has a cable found to be palatable. I searched the Internet while a product which helps to distribute Marder easily. With the product of Cartrend I launched my order. The delivery time was great and I was able to test the product quickly. For almost 2 months, I have not seen a raccoon in my engine room. Every 4 weeks you should spray the area again. A bottle keeps therefore almost a year. I am satisfied and rate it any of the problems with martens has on the vehicle.
