Surface Rust Removal: How to restoring a vehicle's shin

Understanding Rust Types

When a car's metal surface is exposed to moisture, oxygen, and other environmental factors, it can gradually corrode, leading to rust formation. The initial stage of corrosion is usually marked by the appearance of surface rust, which manifests as minor discolouration and superficial rust spots that affect the outer layer of the car's surface. This stage is relatively mild and can be addressed with regular cleaning and maintenance.

However, if surface rust is left unchecked, it can progress to the next stage, known as scale rust. At this stage, the rust has penetrated beyond the surface layer and has started to impact the layers beneath, causing them to corrode as well. Scale rust requires more focused attention to prevent further damage, and it may involve the use of specialized tools and rust removers to treat the affected areas.

The most significant threat posed by rust is penetrating rust, also known as deep rust. At this stage, the rust has reached deep into the metal and can cause irreversible damage if not addressed immediately. Penetrating rust can compromise the structural integrity of the vehicle, making it unsafe to drive. Comprehensive restoration is necessary to prevent further damage and it may involve replacing the affected metal components with new ones. It is essential to regularly inspect a car's surface for signs of rust and address any issues as soon as possible to prevent them from escalating. Proper cleaning, waxing, and maintenance can help to prevent rust formation and prolong the lifespan of a vehicle.

The essential tools for efficient surface rust repair

Dealing with surface rust on a vehicle is a task that can be finished in as little as 30 minutes for small areas. The size and severity of the rust will affect the overall repair time: larger areas or deeply ingrained rust may require more time, and penetrating rust, being more extensive, demands additional attention. To enhance efficiency and save valuable time during the repair process, gather the following tools and materials beforehand:

• Masking Films

Provides a protective barrier to shield surrounding areas from overspray and potential paint drips. Q1® Premium Masking Drop is a paint masking film, the perfect tool to protect the parts of the vehicle that require not to be painted. The HDPE paint masking film has an electrostatic charge to attract the film onto the vehicle surface for a safe application.

• Masking tapes

Use a masking tape, such as Q1® Premium Masking Tape, to secure the plastic sheeting and create defined borders for your repair area, ensuring a clean finish. Q1® Premium Masking Tape is a high-performance automotive masking tape designed for consistent unwinding, easy tear, and conformability.

• Sanding sponges

Fine, Super Fine and Micro Fine, sanding sponges are essential for smoothing surfaces and preparing them for subsequent coatings. Q1® Double Sided Sanding Sponges are coated on both sides and usable on wet or dry surfaces, these sponges feature an innovative abrasive formula combining three different grits for efficient and time-saving abrasion.

• Wire Brush

An effective tool for removing loose rust and paint, facilitating the preparation of the surface for further treatment.

• Wax and Grease Remover

Before applying any coatings, use a wax and grease remover to ensure a clean and contaminant-free surface.

• Lint-Free Cloth or Microfiber Cloth

Use lint-free or microfiber cloths for wiping down the treated area between each step, maintaining a pristine surface.

• Body Filler and Applicator

For addressing deeper rust pits or dents, having body filler and an applicator on hand is crucial to achieving a smooth and level surface.

• Automotive Paint

Choose automotive paint that precisely matches a vehicle's colour for a seamless and professional-looking finish.

How to restore a vehicle from rust

The process of repairing small rust spots on a car hinge on the depth of rust penetration into the metal. For surface rust areas, it takes:

• Cover the vehicle with plastic sheeting, leaving a gap in the size of the treatment area. Tape the sheeting securely to ensure a defined workspace.
• Use wax and grease remover to thoroughly clean the area to be sanded. This step is crucial to prevent contamination during the sanding process.
• Utilize a sanding sponge to eradicate the rust spot and surrounding paint. Continue until you expose the clean, shiny metal base.
• After sanding, use wax and grease remover to prepare the surface for primer and paint.
• Employ a lint-free cloth to eliminate any dust from the surface.
• Apply primer and paint, if necessary.
• Buff the dried coating with a lint-free cloth.

If rust deeply infiltrates or creates perforations, replacement of the affected panel may become necessary. In instances where severe rust issues are encountered, which cannot be effectively remedied through the aforementioned processes, it may be requisite to excise and replace the damaged section of the body panel. While patching with a sheet of metal may be a feasible alternative for smaller areas, replacing the entire panel is often considered more practical.

Your professional fleet deserves the best care to ensure longevity and a polished appearance. Equip yourself with the right tools and products, and take swift action against surface rust. Whether it's a minor touch-up or a more comprehensive repair, addressing rust promptly ensures your fleet stays in prime condition.
