These PSA Sanding Discs are perfect for smoothing metal surfaces prior to polishing. Apply them in grit progression to remove pits, scratches, and surface imperfections.
These sanding discs work great on aluminum and stainless steel. Choose from 120, 180, 220, 320, 400, 600, or 800 grit depending on your project's needs.
Pro Tip:
Start with 220 or 320 grit to remove moderate imperfections. Only use coarse 120 grit for heavily worn or weathered surfaces.
Grit Recommendations:
