Sanding Marks/ Scratches

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
