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:

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

Repair:

1. Allow finish to dry, sand and refinish.

Prevention:

1. Avoid sanding basecoat finishes before clearcoating. If sanding is necessary apply additional color following label direction.
2. 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.
