1. Water Impedes Adhesion: Rustproofing products are typically applied as coatings or sprays to create a protective barrier on metal surfaces. Water acts as a repellent, preventing the product from properly adhering to the car's surface. If the car is not dry, the water barrier can compromise the bond between the rustproofing product and the metal. This reduces the product's effectiveness and durability over time.
2. Dirt Traps Moisture: Dirt, mud, and other contaminants on the car's surface can trap moisture and create pockets of corrosion beneath the rustproofing product. These contaminants provide a suitable environment for rust formation, and the rustproofing product may not be able to effectively penetrate and protect areas where dirt is present.
3. Salt & Chemical Residue: Cars exposed to winter road salts, coastal environments, or industrial areas may accumulate salt and other corrosive chemicals on their surfaces. These substances can accelerate the rusting process, especially if they are not removed prior to rustproofing. Ensuring that the car is thoroughly cleaned eliminates these contaminants and prepares the surface for proper product adhesion.
4. Inspection Accuracy: Cleaning the car before rustproofing allows for a thorough inspection of the vehicle's surface. Any existing rust spots or areas of damage can be identified and addressed before applying the rustproofing product. This helps ensure that the product is applied where it is needed most and prevents rust from spreading.
5. Long-Term Performance: A dry and clean car surface ensures optimal performance and longevity of the rustproofing product. Proper application and adhesion reduce the risk of corrosion and extend the life of the vehicle's metal components. Neglecting to clean and dry the car before rustproofing can significantly reduce the effectiveness of the product and require costly repairs in the future.
Therefore, it is essential for a car to be dry and clean prior to rustproofing to achieve the best protection against corrosion, promote product adherence, and ensure the long-term durability of the rustproofing treatment.
