Scratches from car wash brushes

Definition

Thread-like fine scratches, which are often in parallel lines and are particularly visible on darker colours. The surface has a reduced gloss level and appears grey in shade.

Causes

  1. Hand-wash or carwash brushes which are too coarse and/or dirty
  2. Insufficient pre-wash with too little water
  3. Exposing newly repaired paintwork to a carwash too early. A newly applied coating is less scratch-resistant when the paint has not dried for long enough or when excessive coats are applied, or the wrong amount of hardener is used

HOW TO AVOID

  1. Use suitable and clean brushes
  2. Thoroughly pre-clean the car with plenty of water
  3. Avoid washing the car too quickly after it has been given a new finish (see entry on ‘Aftercare of vehicle paintwork’). Keep to recommended film thicknesses, drying times and amount of hardener.

REPAIR

Polish with Glasurit 562-1602 Fine Polishing Compound and finish with any standard high-gloss polish. Damage caused by carwash brushes cannot be prevented easily. Some cars are supplied with a scratch-resistant OEM clearcoat. We recommend repairing these coatings with Glasurit 923-447 HS VOC Clear, scratch-resistant. Glasurit 923-447 VOC is also suitable for use with other car models.
