Polishing Marks

Description

Abrasive damage to paint surface. 

Cause

Abrasive damage to the paint film due to:

1. Compounding or polishing the surface before fully hardened.
2. Excessive pressure or speed of mechanical polisher.
3. Use of too coarse or ammoniacal compound or incorrect polish, dirty or coarse polishing cloth or mop.

Prevention

1. Allow surface to harden fully before compounding or polishing.
2. Use mechanical polishers at minimum pressure and correct speed.
3. Use the correct grade and type of compound and polish, ensure polishing cloths or mop are soft and clean.
4. Go over polished area with a pre-cleaner and a soft cloth to remove polish residue as a final check.
