Afterward, you should shake the rustproofing product vigorously for one minutes before you begin to apply and shake intermittently during use also. Hold the product and lightly spray it back and forth on the vehicle. For better results, you can spray twice at about a two-minute interval. However, make sure you are not doing this close to open flame.

Nevertheless, you should watch out for any sign of rust on the vehicle, especially on the undercarriage.


Preventing rust on a vehicle is not limited to rustproofing alone. You should properly care for the vehicle and check for any potential rust on it always. Also, rustproof the vehicle once in two years to potentially keep the rust away from it.
