Step 1: Start sanding with Abranet Sic NS 180

This procedure starts with Abranet because the scratches are deep so it is necessary to remove more glass material with coarser grits.

For removal of glass scratches sand with Abranet Sic P180 and Mirka PS 1437 Rotary Polisher or Mirka RPS300CV. Dry or wet sanding. Keep the area as small as possible, since the area will expand for each step.

Step 6: Polish with Polarshine E3 Glass Polishing Compound

Use Mirka PS 1437 Rotary Polisher or Mirka RPS300CV and Mirka White Polishing Felt Pad. Remember to have the polisher flat to the surface and at low speed to not heat up the glass too quickly. Do not let the compound dry on the glass, add more when needed. Wipe the glass and check for scratches. Polish more if needed. Use a soft microfiber cloth and a window cleaning liquid.
