Your RV is one of your major investments, perhaps the second largest after your home. I t is important for you to keep it as long as possible. To do this, an annual rust proofing is essential.
Large vehicles contain more metal and are more exposed to the ground and humid weather conditions. Also, a recreational vehicle is generally used for long drives, in good and bad weather, and on all kinds of roads. If the roads are not paved, the wheels throw earth, sand or gravel at the motor homes.
