Rust – PaintScratch Knowledgebase

Contents

Early Signs: Rust often begins with bubbling and cracking of the paint surface, followed by brown staining as it progresses. Severe rust can include holes in the metal, corroded fasteners and whole sections of the vehicle needing repair. If you have the experience to fix extensive rust, you probably don’t need to read about it! You already know how to use a cutting torch and welder.

Rust Assessment:
- Evaluate the extent of the rust. Surface scratches with minor rust can be treated, whereas bubbling beneath the paint often indicates deeper corrosion requiring more extensive repair.
Removing Rust:
- Use 100 grit sandpaper from our Sandpaper Pack or a wire brush to eliminate all traces of rust. For surface rust, you can even use rubbing compound to remove it. Be careful to preserve surrounding paint.
- For larger area, consider using a drill with a wire brush attachment to expedite the process, available at most hardware stores.
Applying Rust Converter:
- After rust removal, apply Mar-Hyde One-Step Rust Converter to the bare metal to halt further rusting. This converter is available on our site and transforms rust into a stable, paintable surface.
- Follow product instructions for application and curing times to ensure effectiveness.
Surface Preparation:
- Post-conversion, check for any pitting or uneven areas. Use body filler or spot putty to smooth out these imperfections, creating a flawless base for painting.
- After smoothing, apply a high-quality automotive primer to prepare the area for painting. Ensure that sanding post-primer does not remove the protective layer formed by the rust converter.

Regular Maintenance: Promptly treat any chips or scratches to prevent rust formation.
Vehicle Care: Keep your vehicle clean and dry, applying protective wax to shield against environmental factors that promote rust.
Seasonal Considerations: In regions using road salt in winter, increase the frequency of washing and apply additional protective treatments.
