Choosing the right Hand Held Tool For Cleaning Metal On Cars can be challenging. This guide will discuss various methods for removing rust, tarnish, and pits from steel car parts, focusing on handheld tools and abrasives. We’ll explore techniques for achieving a smooth and shiny finish, addressing common misconceptions about sanding steel.
Understanding the Challenges of Cleaning Metal on Cars
Many car enthusiasts believe sanding can smooth steel. However, steel’s hardness makes it resistant to sanding. You can sand surface contaminants, but not the steel itself. For smoothing steel, grinding and polishing are necessary, often requiring tools beyond the scope of typical handheld sanders.
While chemical rust removers exist, a more effective method involves using an angle grinder with a steel wire brush. This approach provides faster and more thorough rust removal.
Handheld Tools and Abrasives for Cleaning Metal
For sanding tasks on steel car parts, several handheld sanders prove effective. Options like the RO 90, DTS400, or DX93 offer suitable performance for smaller objects. When selecting abrasives, consider Granat, Brilliant 2, or Titan. These options provide excellent results on steel. Avoid using Vlies abrasives, as they are less effective for this application.
Opt for a standard sanding pad instead of a hard pad when working on steel. A flexible pad allows for better conformity to the metal’s surface. Start with a 100 or 120 grit sandpaper to avoid deep scratches. Progress to 240 grit for finer smoothing.
Achieving a Polished Finish
After sanding, wet sanding by hand with progressively finer grits (400, 800, and 1200) can further enhance the smoothness. For removing pits in the steel, filling them with a two-part body filler is a common practice, especially if the part will be painted.
Cleaning the steel before any further treatment is crucial. Paint thinner, specifically the type used for oil-based paints, effectively removes residue without leaving a greasy film. Avoid using terpentine for cleaning, as it can leave behind unwanted residue. Remember, protecting bare steel is essential to prevent future rust and dulling. Applying a protective coating after cleaning and smoothing is crucial for long-term preservation.
Conclusion
Cleaning and preparing metal on cars requires understanding the limitations of sanding and the importance of proper tool and abrasive selection. Using appropriate handheld tools, effective abrasives, and the correct cleaning agents, you can achieve a smooth, clean surface ready for further treatment or painting. Always prioritize safety and wear appropriate protective gear when working with power tools and chemicals. Remember to protect the cleaned metal to maintain its shine and prevent future rust.
