Treating surface rust on a car involves carefully preparing the affected area to ensure a smooth surface ready for paint. This process typically focuses on removing the rust and creating an ideal base.
Based on the provided reference, a key part of preparing the surface involves specific sanding and priming steps. These steps are crucial for smoothing the metal and protecting it from further corrosion before the final paint is applied.
Preparing the Surface After Addressing Surface Rust
Once surface rust is identified, the process of sanding and priming helps restore the affected area. Here are the detailed steps as outlined in the reference:
- Initial Sanding: Begin by using 150 grit paper to sand the rusted area. The goal here is to make the area smooth.
- Refining the Surface: Follow up the initial sanding by sanding the area a second time with 200 grit paper. This further refines the smoothness of the surface.
- Cleaning: After sanding, it's essential to wipe the sanded area thoroughly. This removes all dust and debris generated from the sanding process, ensuring a clean base.
- Applying Primer: Once the cleaned area is dry, apply a thin layer of base coat paint primer. Primer serves as a protective layer and helps the final paint adhere better.
- Drying Time: Allow the applied primer layer to dry completely.
- Smoothing the Primer: To maintain a perfectly smooth surface ready for subsequent coats, sand the dried primer layer using 200 grit paper.
These steps are fundamental in ensuring the treated area blends seamlessly with the surrounding paintwork and provides long-lasting protection.
