Here are the different methods of application products undercoats.
1. Spray: The most common method applied dealer sublayer is through the jet. The coating itself is a tar-like thing that "sticks" to the undercarriage elements and acts as a barrier to resist salt, oxygen, moisture, and other elements that lead to corrosion.
2. Electronic: This method involves removing the electrical current capacity of elements under the vehicle. It flows a weak electric current through the material, which reduces the corrosion potential.
3. Dripless spray oil: The last option is to spray anti-drip oil. This is a waxy substance that is applied to the entire vehicle (body and chassis) to provide a sufficiently powerful layer of strength but can wear thin quickly than other conventional methods.
