SANDING MARKS/SCRATCHES

Sanding Marks

Dark and/or streaked marks that resemble sand scratches in the paint film.

CAUSE

Scratching or distorting metallic/mica flakes close to the surface of the paint film due to:

• Sanding single stage or basecoat metallic finishes prior to clearcoating.
  
• Sanding single stage metallic finishes prior to buffing.

REPAIR

Allow finish to dry, sand and refinish.

PREVENTION

• Avoid sanding basecoat finishes before clearcoating. If sanding is necessary apply additional color following label direction.
  
• When sanding single stage finishes confine the sanding to minor imperfections (nib sanding rather than entire panels).
• For best results use 1200 or finer grit sandpaper.
